    Three of a kind

    Please help!

    I have 2 aces in the hole
    Dealer flops 3 cards

    What is my probability of hitting at least 3 aces?

    2/50 + 2/49 + 2/48 = 0.12248


    There are 19,600 combinations of the remaing 50 cards taken 3 at a time.
    There are 2 combinations of the remaining aces
    and 1128 combinations of the remaing 48 cards taken 2 at a time

    2*1128 = 2256

    2256/19600 = 0.1151

    Why don't my numbers match up?

    I'm ready to pull my hair out!


    Thanks in advance

    Try drawing a tree diagram to see it. The two events for each branch are A and A' (Ace and no ace).
