My laptop only has a HDMI outlet and I have a monitor that only accepts DVI and VGA. I bought a cable that goes from the laptop HDMI to monitor DVI and it does not work. Later I realized that HDMI is digital and VGA is analog so it wouldn't work. Should I buy a HDMI to DVI cable? Would it work? How can I connect my laptop to the monitor?

When I connected my Samsung Galaxy S3 to my PC it charges the phone but it doesnt says "Connected as Media Device" or isnt recognized by the computer. Can someone tell me how I can fix this?

How do I find the maximum possible length of a shortest path in an unweighted graph with 7 vertices?

Also, how do i find the minimum number f edges in a spanning tree for a connected undirected graph with 10 vertices?

How many ways are there to form a list of two distinct letters from the set of letters

in the word COMBINATORICS? three distinct letters? four distinct letters?

How many ways are there to form a list of two letters from the set of letters in

the word COMBINATORICS if the letters cannot be used more often than they

appear in COMBINATORICS? three letters?

We want to know how many ways 3 boys and 4 girls can sit in a row.

(a) How many ways can this be done if there are no restrictions?

(b) How many ways can this be done if the boys sit together and the girls sit

together?

(c) How many ways can this be done if the boys and girls must alternate?

How many different three digit positive integers are there? (No leading zeroes are

allowed.) How many positive integers with at most three digits? What are the

answers when “three” is replaced by “n?”

6 cards are dealt (without replacement) from an ordinary deck of 52.What is the probability that at least 2 Hearts are dealt?

Let X be defined as above for α=4.

Define the random variable Y63=∑63i=1Xi, Xi independent identically distributed according to X.

Using linearity of expectation, what is E[Y63]?

Using the fact that the Xi random variables are independent and identically distributed, what is var[Y63]?

What about the the standard deviation std[Y63]?

Using Chebyshev’s inequality, what is a bound on the P(|Y63|>27)?

Let X be a random variable over the integers Z={...−2,−1,0,1,2,...}.

Let P(X=0)=0 and for i≠0 let P(X=i)=1Zα|i|α where Zα=∑∞i=−∞1/|i|^α

For α=2:

What is E[X]?

What is var[X]?

What is std[X]?

Suppose the mean noon-time temperature for September days in San Diego is 24∘ and the standard deviation is 4.9. (Temperature in this problem is measured in degrees celsius)

Using Chebyshev’s theorem, what is the minimal probability (in percents) that the noon-time temperature of a september days is between 14.2∘ and 33.8∘?

On September 26, 1963, the all-time record of noon-time temperature in San Diego of 44∘ was hit. Assume the temperature distribution is symmetric around the mean, what is the Chebyshev bound for the probability of breaking (or tieing) this record?

I am having a hard time understanding this. Could someone explain to me how to do this?

John has a biased coin with P(heads)=0.2. He tosses this coin N times and, out of the N times, the coin lands on heads 140 times. Using Markov’s inequality, he says that the probability of seeing at least this many heads is at most 0.9.

How many times did he toss the coin? N = ? (If N is a fraction, please round it up to the next integer)

Suppose John lends you this coin. If you flip the coin 437 times, what is the upper bound of the probability of seeing at least 273 heads using Markov’s inequality? P(Number of heads>273) ≤ ?___

Can someone please help me understand this problem? I am confused.

Three cards are drawn sequentially from a deck that contains 16 cards numbered 1 to 16 in an arbitrary order. Suppose the first card drawn is a 6.

Define the event of interest, A, as the set of all increasing 3-card sequences, i.e. A={(x1,x2,x3)|x1 < x2 < x3}, where x1,x2,x3∈{1,⋯,16}. Define event B as the set of 3-card sequence that starts with 6, i.e. B={(x1,x2,x3)|x1=6} or simply B={(6,x2,x3)}

Let Sx3=t represent the subset {(6,x2,t)|6 < x2 < t}, then |A∩B|=∑t=816∣∣Sx3=t∣∣.

Then what is |A∩B|=?

There is a class of 315 students taking a T/F quiz of 10 questions. We would normally think it unlikely that a student would get at most 2 questions right out of 10 by flipping a coin, but with a class this large, it might be possible. Here we’ll calculate the probability of at least one student in the class of size 315 getting at most 2 questions right.

What is the probability of every student in the class getting 3 or more questions right?

What is the probability of some student in the class getting at most 2 questions right?

I want to create a video like this:

Suppose we have 15 bins, numbered 1,...,15 and that we have 15 balls, 8 of them white and 7 of them black.

How many white/black patterns can one make by placing the balls in the bins?

Please explain this to me

How many ways are there to form a list of three letters from the letters in the word COMBINATORICS if the letters cannot be used more often than they appear in COMBINATORICS?

Can someone please explain this to me?

An alphabet contains only 5 symbols which we will represent as A, E, R, S, T. (A and E are called vowels, while R, S and T are called consonants). All names are 5 letters long, begin and end with consonants and contain at least two vowels. Adjacent consonants must be the same, while adjacent vowels must be different. How many different names are there?

If someone could explain this to me that would be great!
