    Default Round Robins

    Does anyone know the formula to calculate how many wins you would get for XXX number of losses in a round robin?
    Example...
    If I play 10 teams, and break it into X number of 6 team parlays, if two out of the 10 picks are losses, how many of the 6 team parlays win?

    I've looked for online calculators but they all seem to be either limited to max of 5 picks or only calculate the payout of parlay bets.

    I use this formula to calc. the total possibles:

    N!
    ---- = Tot. combinations
    r!(N-r)!

    that gives me the # of combinations.
    If N=10 (number of picks)
    r=6 (size of parlay)

    10!
    ----
    6!(10-6)!

    10x9x8x7 5040
    -------- = ------ = 210
    4x3x2x1 24


    Now out of the 210 combinations, how many would not contain one or both of the 2 losers? Thus giving me the # of winning combinations.

    thanks in adv.

    Default found calculator

    After taking a break, and then resuming my search, I found this Calc. that will give me the answer. It'd be nice to know the formula used though, so calculations can be done when away from keyboard.

    Put in the amount you wish to bet (remember, this # is multiplied by the # of possibilities).
    Then put in the total # of teams you wish to play, and put in the # of parlays you wish it broke up into.
    The calc. will then give you the payout based on the # of teams that actually won.
