**Questions** There are 3 unfilled male roles in a play, 6 actors including Tom and Joe are auditioning for the
roles, how many different casts including Tom but not Joe?

I thought that since Tom is in and not Joe, the correct equation would be to just do $C\_4^2$ since there is 2 spots left with 4 people available. However, it's saying that the answer is 36. Can someone please explain?
