Have a statistics question for you. Please help. In a class of 24 girls, 7 have blonde hair, 5 have red hair and the rest have black hair. I select a committee of 5 from the class completely at random. Given that exactly two are red heads, find the probability that my commitee contains exactly one blonde?

OpenStudy (anonymous):

It is 1/7 since the red head is 2/5

OpenStudy (anonymous):

I need a bit more than that. How to come to those numbers?
