The geometric distribution is a probability distribution of the number X of Bernoulli trials needed to get one success. For example, how many attempts does a basketball player need to get a goal. Given the probability of success in a single trial is p, the probability that the xth trial is the first success is: Pr(x = x|p) = (1 - p*-'p for x=1,2,3,.... Suppose, you observe n basketball players trying to score and record the number of attempts required...
Problem 5 (10 points). Suppose that the independent Bernoulli trials each with success probability p, are performed independently until the first success occurs, Let Y be the number of trials that are failure. (1) Find the possible values of Y and the probability mass function of Y. (2) Use the relationship between Y and the random variable with a geometric distribution with parameter p to find E(Y) and Var(Y).

We have seen that the geometric distribution Geo(p) is used to model a random variable, X that records the trial number at which the first success isachieved after consecutive failures in each of the preceding trials ("success" and failure being used in a very loose sense here). Here, p is the success probability in each trial. We described the geometric distribution using the probability mass function: f(X)(1- p)*-1p, which computes the probability of achieving success in the xth trial after...
4. Given that X has a geometric distribution, that is the probability mass function is P(X) = p(1-p)x-1 , prove that the mean of the geometric distribution is 1. (Hint: You will have to use the sum of an infinite geometric series)
A discrete probability distribution differs from a continuous probability distribution, by only taking values on a discrete set (like the whole numbers) instead of a continuous set. The geometric distribution is a discrete probability distribution which measures the number of times an experiment must be repeated before a success occurs. For example, in this problem, we will roll a fair six-sided die until the number six occurs, at which point we stop rolling. (a) If we are rolling a die,...
