I like an alternative version of the problem proposed by someone whose identity escapes me.
Thirty students are enrolled in an ethically dubious study. One of them is selected at random to be awakened on the 1st of the month. For the rest, a 6-sided die is rolled. On a result of “1”, each is awakened on a different day of the rest of the 30-day month. On any other result, they are not awakened at all. All participants who are woken are asked to guess whether the die rolled “1″ or not.
What should they guess? Does this differ from the case where the 30 students are replaced by a single participant given amnesic drugs?
