If all four numbers match the four winning numbers, regardless of order, the player wins. What is the probability that the winning numbers are 3, 15, 46, and 49? So the way to think about this problem, they say that we're going to choose four numbers from 60. So one way to think about it is how many different outcomes are there if we choose four numbers out of 60? Now, this is equivalent to saying how many combinations are there if we have 60 items? In this case, we have 60 numbers, and we are going to choose four. And we don't care about the order.
