    a) Order matters since president is different from vice president, so a permutation is used. b) Order doesn't matter since no one player is ranked higher than another. If you state that they play in a certain order, then order would matter. So a combination is used. c) Order doesn't matter as the toppings will all mix in anyway. So a combination is used.

    So basically, a Permutation is used when order is needed, and Combination is when order doesn't matter?
