Xiao Xue asked Ming Ming to play table tennis with her.小雪一直吵著要明明陪她一起打乒乓球。

Ming Ming was troubled and so he had a good idea.明明被吵得實在受不了，于是想出一個妙計。

“Xiao Xue!There are two table tennis balls in the bag.One is yellow and the other is white.Now,you fetch the ball.If you get the yellow one,I will play with you.But if you get the white one,I will quit,and remember you must not trouble me!”“小雪，這個袋子里放了兩個乒乓球，一個是黃色的，另一個是白色的?，F(xiàn)在，你伸出手去拿乒乓球。如果你拿到黃色的，我就陪你玩，但如果拿到的是白色的，你就要放棄，而且不能再吵我了！”

Xiao Xue put two white balls in the bag when Ming Ming was off guard.So,Xiao Xue would get the white one.But Xiao Xue played table tennis with Ming Ming.But do you know why?小雪的眼睛頓時亮起來，但此時卻瞥見轉(zhuǎn)身的明明放了兩個白色乒乓球進去。那么，不論她拿到哪一個都會是白色的。小雪最后還是打了乒乓球。請問你知道為什么嗎？
