THere are 11 people in my family that will be at the Christmas dinner/tree event. We are putting everyone's name on a piece of paper and putting it into a bowl. What is the probability that nobody will draw their own name from the bowl. If they draw their own name, they'll of course need to switch with somebody else. I'm not just interested in the actual probability, but also how to approach this problem.

Thanks. :eek: :p
