WebY follows a negative binomial distribution with parameters n and p, where n is the number of successes needed and p is the probability of success in each trial. Hence, the expected value and variance of Y are given by: E(Y) = np/(1-p) Var(Y) = np/(1-p)^2 WebProblems Introductory. Find the expected value of a dice roll.
