# Math Help - Probability of hand with four aces

1. ## Probability of hand with four aces

A well-shuffled deck of 52 cards is dealt to four players, each receiving 13 cards. Show that the probability of a player receiving a hand with four aces is 0.0026.

I have no idea how to do this.
Thanks

2. Denominator: All possible "deals" of 13 cards to a player are numbers of sets with 13 elements you can construct out of all 52 cards: $52\choose 13$.

Numerator: Of these, the ones with 4 aces in them, are those that you make with all 4 aces and whatever 9 cards left to make a "deal": ${4\choose 4} * {48\choose 9}$
