And so to figure out the probability of winning, it's essentially going to be one of all of the possible, all of the possibilities of numbers that you might be able to pick. So essentially all of the combinations of the white balls times the 46 possibilities that you might get for the mega ball. So to think about the combinations for the white balls, there's a couple of ways you could do it. 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.
