The Big Triple at the local racetrack consists of picking the correct order of finish of the first three horses in the
ninth race. If there are 12 horses entered in today’s ninth race, how many Big Triple outcomes are possible? Place your answer, as a whole number—no decimal places—in the blank. For example 667 would be a legitimate entry.

The order matters, so use permuations:

 

12P3 = 12*11*10 = 1320 triples
