In a competition, only the top 3 horses receive prizes. How many possible ways can a 1st, 2nd, and 3rd prize be awarded if the competition has 12 horses?
A. 36
B. 220
C. 440
D. 1320
Also, is this a permutation or a combination?
Please Help!!
Thank you.

It is a permutation, because the order in which they finish matters. The answer is 12*11*10 = (D)
