You pick 6 numbers from 52. If all 6 of your numbers are picked you share a grand prize pool. If they draw 5 of your #'s you share a second prize pool. If the draw 4 of your #'s you share a third prize pool.
What is the probability you will share in the 1st prize pool?
Since order doesnt matter I found there are 2035820 different combinations, i think thats right.
So is the probability just 6 over that number?
