桥牌打法中经常需要运用概率的知识,可要想将各种分配概率的百分比数字一一记住,实在不是一件容易的事,就连多数的世界大师也不能做到这一点。但那些经常遇到的关于概率大小比较的常识是很容易记忆的,比如单数牌张的分配通常是接近平均的:5张牌2—3分配的可能性最大,7张牌4—3分配的可能性最大……。又比如双数牌张的分配多半是不平均的:4张牌3—1分配的可能性比2—2分配大,6张牌2—4分配的可能性比3—3大……。好了,现在请大家运用这些简单的概率知识,再加上点逻辑推理来看看下面的这副牌吧。
It is not always easy to think of the percentage figures for allotted probabilities in bridge play, and most masters of the world can not do that either. However, common wisdom about the comparison of probability sizes is easy to remember. For example, the distribution of singles is usually close to average: 5-card 2-3 is most likely to be assigned, and 7-card 4-3 is assigned The most likely ... Another example is the distribution of the majority of double-number card is not even average: 4-card 3-1 distribution than the 2-2 distribution of large, 2-4 cards 2-4 is more likely than the distribution of 3-3 ... .... Well, now please use these simple knowledge of probability, coupled with logical reasoning to take a look at the following deck of cards.
