Homework Help: Game Theory question

  1. Apr 18, 2006 #1
    This question has me totally stumped... any help would be appreciated.

    "n players in a game all want to help an injured man. They each get a payoff of 1 if someone helps him, and a payoff of 0 if no one helps him. The person that helps the injured man also receives a penalty of c (0 < c < 1), making their payoff 1-c.

    If n >= 2 and offers of help are made simultaneously, show that in a symmetric Nash Equilibrium, each player will refuse to help with probability c^(1/(n-1))"

    Anyone? I really can't seem to get this :yuck:
