Permutation and Combination

How to solve this equation?

c(8, 3) * c(8, 2) / c(16, 5) = 14/39 ≈ 0.36

There is a standard formula for C(n,r) combinations in your text book.

Apply the formula to each term above (yields a number) and then multiply and divide for the answer

Your previous question shows that you know how to compute C(n,r) and know how to get the right answer for half of the questions.

I copied it from the blackboard in the class. I dont know that you guys will be that hard on this question.

Thanks. Remember to use Google or like reference for formulas as that will jog your memory. I have been out of school longer than you :)
