March 7, 200817 yr A man has n keys of which only one opens his office door. He tries the keys in random order, possible trying the same key several times. Find P®, the probability that he opens the door on the Rth attempt and show that the infinite sum Pr = 1.

Cool, I fucking hate this class : ( I cannot do stats high, and therefore I can't do stats.

Hmmmmm... Seven ?
