1.	7. The ski club with ten members is to choose three officers captain, co-captain & secretary, how manyways can those offices be filled?
Answer» It's a permutation because the order matters. Suppose you pick Bob, Fred,and Alice - that's Bob for captain, Fred for co-captain, and Alice for secretary. I could choose the same three people as Alice, Bob, and Fred; but now Alice would be captain, Bob co-captain, and Fred secretary - a different result for the same 3 people. So the order people are chosen matters.
