    Default Math people, quick questions

    Real quick question.

    Ill make this simple.

    You have 20 envolopes to chose from.
    (3) envolopes each have a value of 0
    (17) envolopes each have a value of 1

    What are the odds to pick the (3) envolopes that hold 0 without picking an envolope that holds a 1

    off top of my head (3/20)(2/19)(1/18)=0.09%

    could be wrong.

    one chance in 1140. Or 1139 to 1 as fair odds.

    PS Same answer as Pico, but put a different way.
