Answer:

The prizes can be given in 1320 ways.

Los premios se pueden otorgar en 1320 maneras.

Explanation:

The order in which the swimmers are ranked is important. That is, A, B and C is a different finish than C, B and A. So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:


P_((n,x)) = (n!)/((n-x)!)

In this question:

3 prizes for 12 swimmers. So


P_((12,3)) = (12!)/((12-3)!) = 1320

The prizes can be given in 1320 ways.

Los premios se pueden otorgar en 1320 maneras.
