A life expectancy of a light bulb is normally distributed, with a mean life of 1600 hours and a standard deviation of 100 hours

If 18,000 of these bulbs are produced, how many will last between 1410 hours and 1760 hours?

What are you guys'?

Of a group of 50 students, 36 enjoy math, 17 enjoy biology, and 6 enjoy both. How many enjoy at least one of these subjects?

I'm stumped, I can't seem to find this method in my book:

You have 9 albums, 1 is a classical album. You take 5 on a trip with you. (order is not important)

a. how many different sets of 5 albums can you choose?

b. how many of these sets would NOT include the classical album?

c. How many of them WOULD include the classical?

I have my personal opinion of this, but I wanna get you guys' take. I'm gonna discuss it in my next vid.

Question 3

Given a committee of 8 women and 11 men, count the number of different ways of choosing a president, a secretary, and a treasurer, if the president must be a woman and the secretary and treasurer must be men. Assume no one can hold more than one office.

I believe its solved by 8*11*10, but could someone correct me if I'm wrong? And give a thorough explanation?

How many odd three-digit numbers can be written using digits from the set {2,3,4,5,6} if no digit may be used more than once?

How many different two-digit numbers can you form using the digits 1,2,3,4,5,7,8(6 intentionally excluded) without repeptition, for example 22 is not allowed?

Another topic that'll be discussed in my next vid. Who'll leave the biggest void in the business when they retire, Randy Orton or Edge?

Wade Barrett, Sheamus, and Drew McIntyre are all without a doubt stars, do you think it's a sign to come that the UK will dominate the industry in the years to come?

How many different numbers can be formed using 4 out of the 9 digits ( 1 through 9) if the numbers:

a. are not repeated?

b. can be repeated?

c.are not repeated but must begin with the digit 2?

d.are not repeated but must begin with the digits 21?

Assuming all members of the club are eligible, but no one can hold more that one office, list and count the different ways the club could elect a president and treasurer if the two officers must not be the same gender.

N={Aaron, Bruce, Carol, Dennis, Eileen}

or {A, B, C, D, E} for short.

1. List the possible pairs

2. And how many ways can a president and treasurer be elected?

I'm doing an all-wrestling oriented channel on youtube, I'll probably do q&a's and reviews and stuff like later on but for now i'm covering some of the themes, just lookin' for a little honest feedback, good or bad.

the equation o the line with the slope and points shown here:

m=2/3, (5,-7)

Anyone know how to write the equation of a circle with center (5, -3) and radius 2?

Thorough rundown much appreciated.

The distance andmidpoint for points (16, -10) and (21, -5). I used the formula my professor gave me and still can't figure it out. Can someone help?

i have a basic acer, and instead of using the mouse, i use the pad, but now it's not working, anyone know the potential problem?

My 360 page keeps saying hidden, and maybe I'm just technology challenged, but I can't seem to make it public. Can someone tell me how?

I wanna hear Y! guys opinions, skinny girls, thick girls, or in the middle AND why. I always love the variety of answers to this question.
