- von Neumann was asked, when about to enter a taxi,
-
- "How thick should a coin be to have equal (=1/3) probability
- of landing on its head,tail,or edge?"
-
- He turned, told the taxi where to go, then answered and was
- away.
-
- Surprisingly, making "reasonable" assumptions, this can be

- The only person from whom I have had an immediate correct
- answer was the late John Leech.

- To standardize on answers, let us assume the answer to be
- Thickness/Diameter.
