probability

A random sample of six integers in the interval [1,42] is to be drawn.
The numbers are selected randomly, one after the other, and repeats
are allowed. What is the probability the six numbers in the sample will
all be different?

  1. number of all possible cases with repetition is
    42^6

    number of cases where they are all different
    = 42x41x40x39x38x37

    Prob (all different) = (42x41x40x39x38x37)/42^6
    = appr .688
