回答: 可不可以说只要发生的可能结果是有限的,则0概率事件就不会发生. 由湘女于 2010-04-22, 07:08:21:

Let x follow standard normal distribution

Ley Y=o if x is irrational number Y=1 if x is a rational number.

Y has only two possible values 0 and 1

P(Y=0)=1 P(Y=1)=0

But Y=1 can happen

Y=1存在，但不会Happen。 (无内容) - DW (0 bytes) 2010-04-22, 11:57:24 (434105)
