[quotefrom="giggshhh"]1. Mr P 知道點數卻不知是那隻牌, 即是那那隻牌一定超過一種花有, 所以只可能以下中的一隻

Hearts A Q 4
Spades 4
Clubs Q 4 5
Diamonds A 5

2. Mr Q 知道花卻肯定 Mr P不知是那隻牌, 即是那種花一定沒有一隻牌是獨有的, 所以只可能是 Hearts 或 Diamonds, 所以只剩

Hearts A Q 4
Diamonds A 5



為何可以一下子剔除左Clubs Q 4 5

呢度一直唔明

題目有問題！

應該Q說P不知道是不根據P不知道來說的！即，Q說一早知道P是不知道的！

如果Q說P不知道是根據P不知道來說的話，那麼Q是說廢話！

P: I don;t know
Q: I know you don't know (after you said you don;t know) (!!!!!) (That is no hints from Q ! everyone know P does not know ! - he already said that)

so....

The actual question is: -

P: I don;t know
Q: Certainly. I already know you don;t know.
P: Oh I know now.
Q: Ah ! I also know now !


Then the question makes sense.
