Binomial Coefficient Calculator
This calculates C(n,k). How many ways can k be chosen from n?
How many possible flop combinations are there? You have two hole cards, leaving 50 cards in the deck. We are drawing three cards for the flop, so C(50,3) = 19,600
possible flop combinations. [see it]
How many possible keno
number combinations are there? There are 80 numbers total and 20 numbers are drawn, so C(80,20) = 3,535,316,142,212,174,000
possible number combinations. (Yes, 3.5 quintillion!) [see it]
