For an art exhibit, Craig has to choose 3 ceramic mugs out of the 7 that he made over the summer. In how many ways can he arrange these 3 mugs in a row?

I'm not looking for the answer, but only an explanation for why this is a permutation problem and not a combination one.
Answered by Steve
because the order or arrangement matters. Otherwise, it'd just be a combination.
