asked • 05/11/211.Q;In a class there are five girls and seven boys. For a school project
the teacher would like to form a group of three students.
What are the chances that there will be at least one female in the group?
This is a straight hypergeometric distribution question.
The answer is 5C1*7C2 / 12C3 where the C's are the binomial coefficients.

Except that it is for "at least" one female, so there could also be 2 or 3. Easier to take the complement of "no females"?05/12/21
