剛剛看到ㄉ...
位啥在第2步驟可以排除到只剩紅心跟方塊.... 想不通阿@@~~ >P先生、Q先生都具有足夠的推理能力。 > >一天，他正在接受推理面試。 > >他知道桌子的抽蛝怞野H下１６張牌: > >紅心：A、Q、4 > >黑桃：J、8、4、2、7、3 > >梅花：K、Q、5、4、6 > >方塊：A、5 > >白教授從16張牌中挑出一隻牌，並把牌的點數告知P先生，再把牌的花告知Q > >先生。即是說，Ｐ只知點數，Ｑ只知花。 > 白教授問P先生和Q先生: > > 你們能否從推理出我挑出的是什麼牌?? > >P先生:“我不知道。“ > >Q先生:“我知道你不知道。“ > >P先生:“現在我知道了。“ > >Q先生:“ＯＨ，我也知道了。“ 解答: 1) P先生:我不知道 Mr.P knows only the point, and statement (1) implies the point that he knew is NOT unique, by that, we can rule out all cards with unique points, i.e. Spade: J,8,2,7,3 Club: K,6 (2) Q先生:我知道你不知道 Mr Q knows only the suit, and statement (2) implies it must be a suit that contains ONLY points with at least two occurences. By that, we know the suit of the chosen card must be either heart or diamond.(不了...位啥只剩紅心跟方塊??) (3) P先生:現在我知道了 Now Mr. P has information about the suit, i.e. either heart or diamond. Since he knows which is the chosen card, the point of this card certainly is not ace, cause if it's an ace, Mr. P still does not have sufficient information to deduct what exactly the suit is (as ace appears in both heart and diamond groups). (4) Q先生:ＯＨ，我也知道了。 Since statement (3) contains information that can rule out ace only, and since now Mr. Q also knows which is the chosen card, the card must be diamond 5. This is because if the suit was heart, Mr. Q by this point could only know that it's either a Q or a 4, and he couldn't be sure which is the chosen one. And since Mr. Q can be sure about this, it must be a diamond 5.
