问题 解答题

三张卡片上,分别写着2、3、4,小明和小丽用卡片摆数,规则是:卡片上的数全朝下,两人任意拿卡片摆出一个三位数.如果摆出的是双数就算小明赢,如果摆出的是单数就算小丽赢.

(1)小丽一定会输吗?

(2)你认为这个游戏公平吗?为什么?

(3)增加一张什么样的卡片才能使游戏公平呢?

答案

(1)2、3、4摆出的三位数的总个数是6种:234、324、342、432、243、423.其中单数有2个,双数有4个,

从可能性大小的角度来说,小明赢的可能性大,小丽赢的可能性小,但小丽不一定会输.

(2)这个游戏不公平.因为组成的这6个三位数中,2个是单数,4个是双数,双方的机会不是均等的,所以说这个游戏不公平.

(3)可以把规则改为:再增加一个单数卡片,如5,那么组成的三位数中,单数与双数的个数就相同,这样就可以公平了.
