This is a factorial problem.
You have three spaces, you have 15 people to choose from for the first space and 14 people to choose from in the second space and 13 people to choose from for the third space.
Also, realize that a group of people #1, #2, and #3 is the same as a group of #3, #2, and #1. So, you need to divide by the possible number of duplicates.
