Chance of two people getting KK?

[LondonBroil]

This happened to me the other night when me and someone else both got KK. I raised pre-flop and he only called. After a flop of AAA and not much else on the turn and river we split the pot.

Anyone know the chances of 2 people getting the same pair?

Well it depends on how many people are at the table. It's easy if there are only two 1/13*3/51*1/25*1/49. That comes out to 3.69378 chances per million. I'm not sure about this but my best guess for a ten handed game is to multiply this by 8 (since there are 8 other people who could have KK). That works out as 29.5502 chances per million. Is this correct?

the chance of another player getting the same pair as you have is (number of opponents)divided by(50 times 49 )

the chance of another player getting the same pair as you have is (number of opponents) times 2 divided by(50 times 49 )

I took the question to be that both had to have Ks not just the same pair. But I agree with your formula. It is the 1/25 * 1/49 part of my post.
