A mathematician and a non-mathematician are sitting in an airport hall waiting for their flight to go. The non- has terrible flight panic.
"Hey, don't worry, it's just every 10000th flight that crashes."
"1:10000? So much? Then it surely will be mine!"
"Well, there is an easy way out. Simply take the next plane. It's much more probable that you go from a crashing to a non-crashing plane than the other way round. So you are already at 1:10000 squared."
