How many ways can the top 5 teams be arranged in a league containing 21 teams? I'm not sure if this is permutation or combination. I think its combination, am I right?
Answered by Elizabeth
Never mind, its permutation because it's the top 5 teams, right?
Answered by Leo
I agree, it is a permutation.

It's a permutation because you care about how they are ordered, not because they are the top five teams.
