Question

To win at lotto in one​ state, one must correctly select 4 numbers from a collection of 61 numbers​ (1 through 61​). the order in which the selection is made does not matter. how many different selections are​ possible?

Answer 1

If order matters, the number is 61 * 60 * 59 * 58 = 12,524,520

Since the order does not matter, the number is 12,524,520/(4 * 3 * 2 * 1) = 521,855
