※ 引述《aspy (未同步)》之銘言：
: There are three sealed and opaque boxes, each containing a ball.
: These three balls are identical except that two balls are reds and one balls
: are green. If you pick the box that containing a green ball,you will receive
: $10,000 in reward. Suppose you picked one of the boxes at random,
: and then one of the other boxes was opened which contains a red ball.
: You are now offered an option to exchange the boxes
: (between the sealed box you picked and the remaining sealed box)
: Should you change your pick? (A detailed analysis is required.)
: (92 成大工管甲.乙)
: 這就是我上次跟你說的很有名的統計題目,今年剛好成大有出,我就把他騰上來了
: 就是跟你上次說的:三人升遷問題類似
: 請問..你覺得應不應該換?
ok，我自己翻一下好了, 設想有以下的一個遊戲
有3各箱子,和1顆球,主持人把這唯一的一顆球放在其中一個箱子裡
如果你翻開的箱子裡面有球,那麼你可以拿到1000元,
如果箱子翻開裡面沒球,那就一毛錢都沒有
問題來了:現在主持人要你先選擇其中一各箱子(但請先不要打開)
然後主持人自己會從另外你沒選的兩個箱子裡,挑其中一個空的箱子打開給你看
之後問你: 你要不要換
如果是你,你會部會換呢?為什麼?
ps:降看起來好像是益智問題阿.....
有沒有人發表一下意見阿~~
因為我也有點搞混了
