    A poker formula question

    I'm curious how to figure out the odds of a flop coming, say, 10 9 9, when one person holds 1010 and the other 109.

    if those are the only cards we are aware of, wouldn't it be (4/52)(3/51)(2/50)(4/52)(3/51)(2/50) = 0.00000328%

    No.. there's only 1 10 left and 3 nines left in 48 cards.
    So it's (1/48) x (3/47) x (2/46) x 100% = 0.0058 % chance. About 1 in 17000 chance of that happening

    here is how you figure this out ...

    52 cards in a deck
    4 cards known (ten ten , ten nine)
    48 cards left in the deck preflop (52-4)
    4 "good" cards (1 ten, 3 nine)

    first card of the flop has a 4 out of 48 chance

    now there is one less "good" card and one less card in the deck

    second card has a 3 out of 47 chance

    now there is one less "good" card and one less card in the deck

    third card has a 2 out of 46 chance

    ---------

    (4/48) * (3/47) * (2/46)

    That explains it.
