In a room stand n armed and angry people. At each chime of a clock, everyone simultaneously spins around and shoots a random other person. The persons shot fall dead and the survivors spin and shoot again at the next chime; eventually, everyone is dead or there is a single survivor.

As n grows, what is the limiting probability that there will be a survivor?
