Question

How many three person commitees can be made with 8 members

Answer 1

56

Explanation:

The formula to solve this is n! / (k! (n-k)!), where n = 8 and k = 3. Therefore, when we fill in the numbers we have:

8! / (3!(8-3)!)

This becomes

40320 / (6 * 5!) = 40320 / (6 * 120) = 40320 / 720 = 56
