紅心:A、Q、4
黑桃:J、8、4、2、7、3
梅花:K、Q、5、4、6
方塊:A、5

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。

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。“

[updated:LAST EDITED ON Jul-28-03 AT 07:48 PM (GMT)]P如果知點數係2,3,7,8,J就會知花係咩
所以P話唔知花係咩就一定係只知點數係4,5,Q,A

Q第二句話知道P唔知,係因為佢係花係黑桃..
Q意思只係笑P仲未知

但Q估唔到P會搏一搏話知(引蛇出洞)
Q一心急以為P知,爭答自己又知..亞P就因為咁知Q只會知花係黑桃先會知答案,
(如果Q知道花係其他三種都唔會知答案)

首先P 剩係知數字,佢講唔知o既話,即係果個字o係其他花都有存在啦!
咁就可以撇除單丁果D 數字喇!
紅心:A、Q、4
黑桃:4
梅花:Q、5、4
方塊:A、5

跟住Q 知道P 唔知,即係果種花入面所有數字都有o係其他花度出現啦!
符會呢兩個條件只有兩種花︰
紅心:A、Q、4
方塊:A、5

最後分析︰
隻牌係A o既話,兩個都唔會估得中,
隻牌係紅心Q 或者4o既話,Q 就冇可能估得中,
要兩個都推理得到o既只有"方塊五"一隻。
Right?

Q就唔會肯定P知or not.但係而家Q話知都P唔知.咁即係一定係紅心or方塊!

無野啦我明啦...
梅花同黑桃唔得係因為
只有Q知道花係紅心或方塊, 先可以話P一定唔知...
因為紅心或方塊所有牌都有同其他花重覆,
所以P一定唔會知邊隻...

呃左POST, sorry...
係呢道想唔通..出面又無人解得明...
