Remark

It's a permutation question, Order does not matter.

Answer

Most people will try and tell you that the answer is 20 * 19. That would make a pure pure permutation question. The problem is that the actual answer is 20 * 20 because she can have 2 scoops are the same. I would still answer permutation but be prepared to get it incorrect.
