Hypergeometric Distribution (Optional) · Exercise 6

A group of martial arts students is planning on participating in an upcoming demonstration. Six are students of tae kwon do, and seven are students of shotokan karate. Suppose that eight students are randomly picked to be in the first demonstration. We are interested in the number of shotokan karate students in that first demonstration.

(a) In words, define the random variable X.
(b) List the values that X may take on.
(c) Give the distribution of X. X ~ _____(_____,_____)
(d) How many shotokan karate students do we expect to be in that first demonstration?

Its source prints no answer for this problem, so there's nothing to check against.
