Homework Help: Probability problem

  1. Nov 30, 2006 #1
    1. The problem statement, all variables and given/known data

    probability to achieve a couple of 6 launching a couple of dies for 24 times

    2. Relevant equations

    why i cannot calculate this as:
    1/36 * (35/36)EXP23 * (24!/23!)


    3. The attempt at a solution

    it should be correct:
    a="to achive a couple of 6 in 1 throw"
    e="never achive a coule of 6 in 24 throws"
    i can calculare p(a)=1/36
    i can calculate p(e)=[1-p(a)]EXP24
    so 1-p(e) should be my correct result

    Unless I'm missing something, it seems you can treat this like a Bernoulli scheme with the probability p = 1/36.

    i understand by myself

    the exact text is of the problem is:

    probability to achieve AT LEAST a couple of 6 launching a couple of dies for 24 times

    so now i understand why i cannot use it

    thank you
