Suppose that 30% of all students who have to buy a text for a particular course want a new

copy (call this a "success"), whereas the other 70% want a used copy. Consider randomly

selecting 20 purchasers.

a) What are the mean value and standard deviation of the number who want a new copy

of the book?

b) What is the probability that the number who want new copies is more than two standard

deviations away from the mean value?

c) The bookstore has 15 new copies and 15 used copies in stock. If 20 people come in

one-by-one to purchase this text, what is the probability that all 20 will get the type

of book they want from the current stock? [Hint: Let X=the number who want a new

copy. For what values of X will all 20 get what they want?]

Note: I got Part A to be 2.049

My ex and I had been talking because we still hangout and even do "stuff" even tho were technically not together anymore. Well this saint patricks day we were both going to different parties. Apparently she had way too much to drink because at some point late that night her "bestfriend" whose a guy ended up making out with her. Things then progressed to him giving her a hicky and fingering her. Well she told me today and she said that they are not friends anymore and that shes deeply sorry and regrets it completely and loves me and wants me and all that. It did sound earnest, but I can't bring myself, mentally or even emotionally, to care anymore. She really betrayed my trust completely. I even told her that idk if i can forgive her and that she'd have to completely earn back my feelings, trust, respect, love, everthing. Were sposed to be prom dates, but im really taken aback by this whole ordeal. I dont even think i can touch her let alone go to prom with her. The guy she did this with has a history with her, but till now they havnt acted on it at all. They were both drunk but hes the one that kinda forced it and she was too drunk to stop it. Thats not an excuse tho. She even told the kid they cant be friends anymore, but i just dont know. She said that she wont even go to partys anymore unless i go with her and that i can get even and just do some chick but i cant bring myself to do that type of thing to some girl. Im really hurt by what she did, and despite her efforts i dont think i can forgive her. What do you guys think, should i give it some time and let her try to earn me back or just cut her off completely?

I recently started talking with this girl a couple weeks ago. We've hung out three times and have already made out. We've also established that we're "talking" and that we both like eachother. My problem is she parties like two or three times a week. Don't get me wrong, i love to drink and smoke too but not that much. She said she could probly see us being boyfriend/girlfriend if we get to know eachother more, but some of me doesn't really want that. The thing is its to the point where she is unintentionally injuring herself while drunk or high. I see this as a life problem. I've only known her for two weeks and in that time she slipped on ice while drunk and broke a couple wrist bones, and tonite she thinks she might have broken her toe while high (except she was still high when she told me so who knows for sure). Because she parties a lot I dont think I can really respect her and view her as my potential girlfriend. This wouldn't be fair to me or her, but the rest of me is just saying just try it, nothing bad could really happen. Plus we have made out so it can only get better from here. I just dont know what to do. Out texting conversations are okay, but we dont have a lot in common so sometimes i cant even think of stuff to talk about. However, when things are going good, our conversatioins are amazing, each one has a smiley face, and when we're physically around eachother we connect so well. Maybe some thoughts on the situation anyone?

So this girl and I started talking and hanging out with eachother. We never previously knew eachother till just recently. We text eachother everyday and she mostly texts first. We've hung out together three times. We went to a movie the first time and got to know eachother better. Then we played mini golf and watched TV the second time on my couch. This night ended in us kissing twice. Then today we hung for like two hours and made out a lot before she left. Where do I take it from here, I mean what happens next time? Should I go for her bra or slow it down since technically were just "talking" i guess?

So this girl and I have commented back and forth a bit over facebook, but literally probably under 10 comments and theyre all at different times. After commenting on one of her posts she messaged me one night about how we should talk more, so we exchanged numbers and started texting these last two days. We both go to the same school, but weve literally never talked in person or anything so I barely know her. Somehow, while flirting back and forth through text she mentioned doing something together, so we started talking about when we were available this weekend. So long story short were seeing a movie sunday night. The only problem I cant think of anything else to talk to her about through text. Weve talked about music, what we do for fun, where we work, introductions, stuff about ourselves, to what we think about eachother, everything i can think of. I've run out of stuff and I need to keep things going until our date on sunday. I need help with some subject matter, this girl is pretty cute and I wanna keep things moving with us.

So I went to my schools football game tonite and I painted my chest with a couple of friends cuz were seniors. The thing is my ex is a cheerleader and she literally said hi to every guy around me, which are all my good friends, except for me. She avoided looking at me completely. Like I don't care at all about her and I havnt actually talked to her in probly a month; hell I even deleted her number. It's not like it matters tho cuz she doesn't make an effort to contact me either. Not to mention that her new boyfriend was at the game and he doesn't even go to our school. The funny part is he isn't really involved in any of the school cheering/togetherness that is a football game. It's just kinda frustrates ne that she can talk with and invite and text my friends all the time and yet completely ignore me like I don't exist. Wouldn't that annoy you?

Me and my now ex-girlfriend broke up. well actually she broke up with me and over the phone which makes it all worse. We werent together for a really long time, but long enough for me to fall in love. She was different, she was someone I saw myself going out with for at least a year and somehow it all fell apart. She said she lost her feelings for me and tried to get them back but couldnt. I think thats crap because she didnt even make an effort to be with me for like a month. When she called to break up she was crying like crazy and it made me not be able to say anything cuz id feel like a total dick. So I texted her the next day with all the crap she put me through and all the reasons why i was pissed and sad because i needed closure. We texted back and forth for about 15 texts and then she admitted that she didnt want it to be like this, she wanted us to become good friends then eventually try again. I told her that i didnt think that was possible with all that happened and asked her how anything would even change. She basically said that it worked for awhile and that we already knew like everything about eachother and that she doesnt believe that "love" works for her. She said she liked me a lot and that time heals everything. Then when I said that i didnt understand how if we tried again later if it would be any different. She told me there wasnt any guaentee, so I told her that thats why itll just happen all over again. She never responed back. I got rid of all the stuff that she gave me cuz it hurt to even look at it. I dont talk to her at all, and she even texted my friends and told them that it was best she not really talk to them anymore either. She not only broke up with me, but also with my friends and who were her friends. My heart tells me that i need her and id like to get back together with her later on, but my brain tells me that ill just get hurt all over again. She told me that she didnt believe in love and that there was no guarantee that she wont ruin her feelings again. Im torn...how do i make it stop!

My girlfriend usually texts me a smiley face after saying good night, but I think she took something I said right before out of context, because after night she put :*

So this girl and I have known eachither since the start of the school year and have started to build up feelings for one another. It started out playfully but I didn't think it would amount to anything since I didn't even have her number. Later on she needed a ride to cheerleading practice and she noticed my phone in the car and asked for it so she could put her number in it. Since that night we've texted eachother every night and one night I called her because she just wanted me to talk with her. We were on the phone for an hour and 20 min which is crazy long. So far I've just gone sledding with her once and I didn't know she wanted a real relationship because everytime I talked about something fun or hanging out she assumed it was with friends also. However today she invited to watch titanic with her this Saturday. So I know that she does like me and might want a relationship out of this. I expect some cuddling, a hug goodbye at the end, but hope for a kiss maybe. What do u guys think? Also I have never been in this situation what should I do/say once there, I definitely wanna avoid any awkwardness.

Me and my friends love playing padiddle now whenever we drive at night. Usually were split on teams of boys vs girls and of course my team always wins (boys). I'm just curious wat other kinds of strip car games u can play cuz they're really fun.

Should I get the Burton Gig Bag or the Burton Space Sack? I want padding so I don't screw up my board or car and Ive read that usually most bags are made so that u can have ur bindings on the board while it's in there but wat about the boots. I have a 155cm board and I'm thinking about a 166cm bag so I can fit other stuff, they have a 157 but I think that'd be too tight. Any help would be appreciated; especially if they have one of these bags.

I'm 5ft 8in and i ride a 155cm snowboard. My board is centered and i ride in a duck stance. But my toes hang over the edge about an inch and a half. i think thats way too much so would it really mess me up that bad? Its a K2 Anagram and i wear Large K2 Sonic Bindings and size 11 Deeluxe Boots.

This girl and i are getting kinda close. She's my homecoming date and i do kinda like her. Last weekend i needed to pick out my stuff for homecoming and i asked her to come with so i can pick the right colors. We went to the mall at like 1:30 and i thought it would be a quick 1hr - 2hr thing but after that we didn't wanna go home and her mom said she had to be home by 11:00 so we saw like 3 movies that day and only got home at like 9:30. We talked a lot and joked around and through like 2 of the movies i had my arm around her and we kinda snuggled up together. Then next week were going to the movies again to see stepfather, just me and her again. I think we could be a couple if i really wanted. What are your guys thoughts on the whole thing? I think depending on how things go at homecoming we could be a couple.

I was thinking either the 2010 K2 Brigade or the 2010 5150 Nomad. I wanna spend less than $350, and I'm also up for suggestions on other boards as well. I've been snowboarding for two years.

So like a month ago i went to this girls house and before leaving her friend told I should ask our mutual friend, the one whose we were at, to the hmecoming dance so I said y not and I did. Homcoming is in 2 weeks and two of her friends heard and today at a football game one of her two friends started talking **** about me cuz everyone keeps saying that we should just go out. And it kinda bothers me and pisses me off cuz I never did anything wrong to provoke the trash talking and now I'm thinking that y should I even go to the dance with her. If I gotta continuously hear this and just bcuz Im going with her to the dance. I used to kinda like he last year but this was more like a pity date asking. So what I'm asking is your opinion on this and if I should even bother going, cuz now I don't even feel like it.

So I asked this girl to homecoming. I've known her awhile and her best friend said I should ask her so I did. But homecoming is in a month, so since I'm taking her to homecoming does that mean we are a couple now? I"m confused. I mean if were not gf and bf then if one of us gets into a relationship then it'd be kinda weird to go to homecoming together. So that means that we are a couple. Its just that it doesnt feel like we are. We were texting eachother yesterday and i had to go to work so i said ill talk later or something then she said back okay just text me after or something. So does that mean she is as confused as me on what we are or she just said that cuz i did.

For the past couple of weeks I've been having dreams in which I just randomly start making out with chicks. Actually they're the ones that start and then I have a should I and shouldn't I discussion with myself and then make out with them. They're not girls I know very well more like the girls that u know because u know their friend.

I was just wondering if being able to sing well would be a turn on. See I've sung in front of some friends before and they said I'm pretty good. I like singing, mostly pop punk because it fits my voice well. Like all time low, mayday parade, hit the lights stuff. I never sang in front of any of my friends that were girls tho cuz sometimes I'm a little shy about it but I just wanted to know. And I know some of u will say that guitar playing with singing is even better but I'm working on that since I just started playing guitar.

I have a woodshop class in highschool and for our second quarter project i have to make whatever i want from wood. I was thinking y not make a snowboard. I don't think it would be too hard. But now i can't find any sites where there are woodworking plans on how to make a snowboard. Any ideas? And if that doesn't work out maybe give a couple suggestions on making something else? I was thinking maybe making something for my girlfriend.
