Hi, can someone help me answer the following problem?
In a softball tournament, games are limited to 6 innings and players are restricted to at most 1 bat per inning. Let Y be the number of times a player bats per game with a binomial distribution and probability of 0.8. The number of hits he gets, X, also follows a binomial distribution with probability 0.3.
Find the mean and variance of X.
Thanks for your help!
