Včera večer jsem vzal stopaře.
Povídá mi: "To se nebojíte, brát takhle v noci cizí lidi? Co kdybych byl sériový vrah?"
Já na to: "Prosím vás... víte, jaká je šance, že se sejdou dva sérioví vrazi v jednom autě?"

Again, speaking of probability, there is the story of the statistician who told a friend that he never takes airplanes. When asked why, he replied that he computed the probability that there be a bomb on the plane, and that although the probability was low, it was too high for his comfort.
A week later, the friend met him on a plane and asked him why he changed his theory. He replied: ‘I didn’t change my theory. It’s just that I subsequently computed the probability that there simultaneously be two bombs on the plane. This is low enough for my comfort, and so I now carry my own bomb.’
