3. A school club consists of 20 male students and 11 female students. If 4 students are selected to represent the club in the student government, what is the probability 2 will be male and 2 will be female? Hint: Hypergeometric Answer. n = 4, a = 20, b = 11, a + b = 31, k = 2 . 3. A school club consists of 20 male students and 11 female students.

Explanation / Answer

This would be answered based on the hypergeometric distribution and calculation would be as follows: -

20C2*11C2/31C4

190*55/31465

0.3321
