ABSTRACT
Before you are two boxes: a transparent one containing £10,000 and an opaque one which contains £1,000,000 or nothing. You have a choice between taking the opaque box alone or taking both of them. A Predictor with a highly successful record predicted whether you are going to take both boxes or just one. If he predicted that you will take just the opaque box he has put a million in it: if he predicted you will take both boxes he has left the opaque box empty. And you know this. Should you take one box or two?
