I have a video here on solving combination and permutations problems using StatCrunch, but here is the basic Excel solution for problem 3.4.51 in MyStatLab homework which just requires the use of **combinations since order does not matter**.

Remember the fundamental counting principle says that if Event A can occur in m ways and Event B can occur in n ways, the number of ways Event A and Event B can occur is m*n.
