這是最近遇到一個問題
我找了一下之前的文章
不知道是否有高手解過
============================================
有六顆球顏色分別為藍 藍 藍 紅 紅 黃
另外有甲乙丙丁四人
每人各抽其中一個球
甲乙丙丁四人都可以看到其他三人的球之顏色
卻不知道自己的球顏色為何
甲說:「我不知道自己拿的是什麼顏色的球」
乙說:「我也不知道自己拿的是什麼顏色的球」
丙說:「我也不知道自己拿的是什麼顏色的球」
丁說:「我也不知道自己拿的是什麼顏色的球」
當丁說他不知道的同時甲卻開口了
甲說:「我知道自己拿的是什麼顏色的球了」
乙說:「我也知道了」
丙說:「我也知道了」
丁說:「我也知道了」
請試著解釋並推理其過程
