The Android mobile game "Pocket Tanks" has 295 unique weapons. For each match, 20 weapons are inserted into a list. Of those 20, players alternately draw weapons until all are exhausted, leaving each player with 10 weapons.
I'm trying to think of how many combinations of weapons exist. Is this "(295 choose 20) choose 10"? If so this evaluates to an extremely large number. It's large enough that "(295 choose 20) choose 10" in WolframAlpha can't evaluate. You have to calculate the first parenthetical, then evaluate the remaining piece.
