Homework Help: Which distribution to use?

  1. Oct 24, 2011 #1
    1. The problem statement, all variables and given/known data
    The probability of an experiment is p. Show that the expected number of trials for two successes in a row is [itex] \frac{p+1}{p^2} [/itex]

    I just don't know what distribution to work with here.
