there are 8 students auditioning for a play and there are 56 possible outcomes. How many roles are there?

I am trying to help my son and I understand the question -just not sure how to get there as I am not understanding probabilities and combinations which I believe this is.
There are 8 ways to choose the first role, leaving 7 ways to choose the 2nd role, 6 ways for the 3rd, etc.
8*7 = 56, so we must have just two roles.
