The moment generating function ф(t) of random variable X is defined for all values of t by et*p(x), if X is discrete e f (x)dx, if X is continus (a) Find the moment generating function of a Binomial random variable X with parameters n (the total number of trials) and p (the probability of success). (b) If X and Y are independent Binomial random variables with parameters (n1 p) and (n2, p), respectively, then what is the distribution of X...
3. Use the probability generating function Px)(s) to find (a) E[X(10)] (b) VarX(10)] (c) P(X(5)-2) . ( 4.2 Probability Generating Functions The probability generating function (PGF) is a useful tool for dealing with discrete random variables taking values 0,1, 2, Its particular strength is that it gives us an easy way of characterizing the distribution of X +Y when X and Y are independent In general it is difficult to find the distribution of a sum using the traditional probability...

Find any x- and y-intercepts for the specified interval. Show work. b. Find any horizontal and vertical asymptotes. Show work. c Give the intervals in interval notation where the function is increasing and where it is decreasing for the specified interval. Show your work. You may show your work in...
I only need help with part B. I need help with the sketch and all of B, not just the first part (like others have answered previously.) THIS IS THE PART I REALLY NEED HELP WITH 1.
