标题[问题] 互斥事件与独立事件
时间Fri Nov 28 02:11:47 2008
统计课本里面写到的
Do not confuse the notion of mutually exclusive events with that of indepedent
events. Two events with nonzero probabilities cannot be both mutually
exclusive and independent. If one mutually exclusive event is known to occur,
the other cannot occur; thus, the probability of the other event occuring is
reduced to zero. They are therefore dependent.
勿将互斥事件和独立事件混为一谈
可是统计课本上面没有例子
有谁可以用例子来解释这个概念??
谢谢:)
