How the odds are worked out
The chance of exactly k hits when you pick n numbers is the number of ways to choose k of your numbers and 10 − k of the other 40 − n, divided by every possible draw of 10 from 40. This is called the hypergeometric distribution. Return to player is each multiplier times its chance, added up.
