Description

睡美人问题:睡美人将在星期日晚上睡去,而在睡前她被告知实验详情:在她睡去后会由抛硬币来决定她将醒来一次或是两次。如果硬币为正面朝上,她会在星期一醒来并接受采访;如果为反面朝上,她则会在星期一、星期二各醒来一次并分别接受采访。无论硬币正反,她每次睡去时都会被灌下失忆药,不再记得自己是否曾经醒过。同时,她在接受采访时也并不知道这一天是星期几。在她每次接受采访时,都会询问她:“你现在有多确信之前抛出的硬币是正面朝上?”喜马拉雅FM:https://www.ximalaya.com/keji/6310606/  (欢迎加入Ximi团)微信关注:dalaoli_shuxue B站: https://space.bilibili.com/423722633 知乎:https://zhuanlan.zhihu.com/dalaoli-shuxue/
