If you are used to thinking in combinatorics terms, it would essentially saying, well, out of a set of 56 things, I am going to choose five of them. So this is literally, you could view this as 56 choose five. Or if you wanna think of it in more conceptual terms, the first ball I pick, there's 56 possibilities. Since we're not replacing the ball, the next ball I pick, there's going to be 55 possibilities. The ball after that, there's going to be 54 possibilities. Ball after that, there's going to be 53 possibilities. And then the ball after that, there's going to be 52 possibilities.
