I got as far as (13) (12) (11) (10X2) and got the question wrong Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! The first three are fine. There are then 10 people left, two of whom will win the same prize. This has 10C2 or 45 ways of happening, so that is the fourth term
13*12*11*45=77220
