    Durito , Ganch or anyone.... Math question

    I forget how to do this...

    Let's say there's a 33.333% chance of team A winning


    With that above statement

    What's the probability of them winning ...


    A. 7 of 15 times
    B. 8 of 15 times
    C. 9 of 15 times
    D. 10 of 15 times


    What's the probability of them losing:

    E. 13 of 15 times
    F. 12 of 15 times

    In Excel, the probabilities of the team in question winning or losing exactly the number of times specified:
    1. =BINOMDIST(7, 15, 33.333%, 0)
    2. =BINOMDIST(8, 15, 33.333%, 0)
    3. =BINOMDIST(9, 15, 33.333%, 0)
    4. =BINOMDIST(10, 15, 33.333%, 0)
    5. =BINOMDIST(13, 15, 66.667%, 0)
    6. =BINOMDIST(12, 15, 66.667%, 0)


    In general the probability of winning exactly W games out of N given a single-game win probability of p is:
    =BINOMDIST(W, N, p, 0)
    And the probability of winning at least W games out of N given a single-game win probability of p is:
    =1-BINOMDIST(W-1, N, p, 1)
