Hello
I know this isn't strictly the right sort of post but it's interesting
and is doing my head in...
100 passengers are queuing to get on a plane.
Each has a ticket with a seat number and they are standing in order.
The first man in the queue is crazy and will sit anywhere at random.
The rest of the passengers will sit in their own seat, unless it is not
available, in which case they will sit in another seat at random.
What is the probability that the 100th passenger sits in his own seat?
I'd appreciate proofs or good reasoning.
The best most correct answer gets a special prize (a McDonald's
voucher!).
Regards
