海外に行ってる友人からこんなんが。
I have three boxes. In one I put a prize, and two are empty. I then mix up the boxes. You want to pick up the box with the prize in it. You choose one box. I then open another one of the boxes and show that it is empty. I then give you the chance to change your choice of boxes-should you do so? How is this puzzle related to the Three Prisoners problem? 会社の研修の宿題だそうですが、なんか懐かしい問題じゃありません？＞常連の皆様 |
