Abe, Raith and Ghost are to commit 7 sins on earth altogether. But they can't remember all of the types, so they agree that one sin is as good as any other. If they each want to commit at least one sin on earth, how many different ways can they split up the work?

This is the same as distributing 7 identical balls into 3 distinct boxes.

 

The formula used for this kind of distribution is: (P - 1) nCr (K - 1) =(7 - 1) nCr (3 - 1) =6C2 =15 ways.
