Raising from the dealer position.
 
Did I figure this out correctly. Assume that three people are dealt two cards from three completely different decks. They can be dealt exactly the same hand. Now I will rank each two card hand all 1326 combo's from high to low. It is unimportant to me what the ranking system is. Suppose I have two cards that are exactly at the 40th percentile.

Is the probability that I have the best hand.

1-((2*.40)-(.4*.4)) = .36 or 36 percent of the time I have the best hand.

Thanks, Cobra

When I say 40th percentile I mean 60 percent of the hands are worse than it and 40 percent are better.

If you strip away all the card references, does this question basically boil down to "There are 100 numbers in a hat, three people pick a number and replace it...what are the odds that if I pick 60, it's the highest number of the three?"

If so, I'd say 34.81% of the time you'll have the best "hand" or whatever.

Yes LetYouDown, that is what I am asking. If you don't mind how did you come up with that answer. I am more interested in how the answer was derived than the answer itself.

Well, we know you'll pick 60. So you need the other two people to pick 59 or lower. They both have a 59% chance of doing this. .59 * .59 = .3481 or 34.81%.

Boy that was easy wasn't it. Thanks, Cobra
