Thread: Probability in a game of Bridge

I've researched this quite a bit. First off I'll post the problem then I'll show you some of what I think the work is to prove that I've attempted it.

The question:
In a bridge game each player has 13 cards so you and your partner have a total of 26 cards. What is the probability that you and your partner have exactly x Aces when x equals 0,1,2,3,4.

MY WORK (so far):
4/52 * 3/52 * 2/52 * 1/52 (this would be the equation IF you were only given 4 cards). Right??? Or is it something like (4!/52!). Totally confused.

We now have to add on the odds considering that you are getting 22 more cards which would be something like this...
48/52 * 47/52 * 46/52 * 45/52 * 44/52 * 43/52 * ......... * 28/52 * 27/52. Can you help me finalize this please? I've researched all over gooooogle and everywhere else I can think of.

I tried Probabilities Miscellaneous: Bridge Odds to get some insight but that didn't help me either.

Hello, cunoodle2!

Your fractions are wrong.
You can't keep the denominator (52) constant.

There are: . possible outcomes.


There are 4 Aces in the deck, and 48 Others.

To get exactly Aces, there are: . ways.
We want cards from the 48 Others: . ways.
