Question

Quizplus · Accepted Answer

A hypergeometric distribution is used to model the probability of a certain number of successes (in this case, selecting males) in a sample of a fixed size (in this case, 5) taken without replacement from a population with a known number of successes (males) and failures (females). Therefore, the number of males selected from the given class of students without replacement follows a hypergeometric distribution.
