The odds on big pairs
Anyone know the percentage or odds on, if I have a big pocket pair (jacks or better) the odds that one of my opponents in a full ring game will also have a big pocket pair (again jacks or better.
Really need this info, thanks ahead CASHIZ |

Re: The odds on big pairs
Here is a quick way to get a rough approximation: The average number of other big pairs you are up against is 9*19/(50 choose 2) = 171/1225 = .13959. That is greater than the probability you are up against a big pair because there may be more than one. To estimate the probability, the probability that a Poisson distribution with mean x is greater than 0 is 1-exp(-x). 1-exp(-171/1225) = .130287.
That isn't exact because the Poisson distribution is a rough approximation here. I'm not sure it is even better than 1-(1-19/1225)^9 = .131238, which assumes your opponents' hands are independent. If I get bored, I may do the exact calculation later, using this method. However, I think these estimates are off by less than 0.2%. |

Re: The odds on big pairs
I'm really bad at math, does that mean 2 percent. Can you please elaberate a little more. It seems to me just out of experiance that it happens quite often that you have a big pair and so does one of your opponents. Of course you don't see every hand but just for example i've seen it four times in the last 6 hours.

does that mean 2 percent [/ QUOTE ] .131 = 13.1%, or between 6:1 and 7:1. The 0.2% I mentioned was an error estimate for the technique I used. Rather than saying the probability is exactly 13.1%, I'm claiming that the probability should be between 12.9% and 13.3%. |
