- From ``Ask Marilyn'' by Marilyn Vos Savant, Parade magazine, December
- 13, 1992.
-
- You have a hat in which there are three pancakes. One is golden on
- both sides, one is brown on both sides, and one is golden on one side
- and brown on the other. You withdraw one pancake and see that one side
- is brown. What is the probability that the other side is brown?
-
- ---Robert H. Batts, Acton, Mass.
-
- It's two out of three. The pancake you withdrew had to be one of only
- two of them: the brown/golden one or the brown/brown one. And of the
- three brown sides you could be seeing, two of them also have brown on
- the other side.
