Lottery Math
members.cox.net - The odds of a "Lotto" style lottery can be found with the formula: n! / (n - r)! r! where n is the highest numbered ball and r is the number of balls chosen. This is called in math a combination. An easier way to think about it is if there are 40 balls and 6 are chosen, there are 40 possible numbers that can come up first, leaving 39 that can come up second, then 38, 37, 36, and finally 35 on the final number.
