    选中老婆的概率(换还是不换)

    看你是否懂得概率的精髓?    
     
    问题:
     
         有三扇门,惟有一扇门后面站着自己的老婆;
     
         现在你已经选择了一扇,这时知道详情的PAPA打开另外两扇门之一,当然后面站的不是你的老婆。
     
         此时,你是坚持原来的选择还,是改变投奔另一扇?分析换与不换,哪个成功率高?
     
    请在留言处留下你的答案.
     
    答对者有饭吃哦!

    1.如果想证明我的选择是错的,papa只要打开正确的门就可以拉,既然他无法证明,那就是说,我100%选对了咯,不换
    2.如果不是1,那么正确的概率也是对半开,也不换
    3.打死也不换

    因为你是故意打开那扇门的,所以你选到“我老婆”的概率当然是0,而我选到“我老婆”的概率还是1/3,这样另一扇门后有“我老婆”的概率自然就是2/3,所以当然应该换咯!!!
    来请客吃饭!!!~~
    哈哈~~
