A sample space consists only of 2 events,A and B.Which of the following would we use to describe A and B if they cannot occur at the same time?

b.P (A and B)=0
c.Collectively exhaustive

答案是D
这个题目说的是两事件互斥,因此选择第四个.
选项 a和b好像都对吧
选项D 都对
一个样本空间只包括2事件,A和B,我们将使用下面描述的A和B,如果他们不可能同时发生的?
A.相互排斥
B P(A和B)= 0
C对立事件
D.以上
应该选D
d,这问题问到米国佬哪儿去了,问A和B不同时存在的情况:A互斥,B概率表示,C对立事件,都满足,选D以上都合适。
D
因为不能同时发生,所以是互斥的,Mutually exclusive正确,P (A and B)=0也是对的
A和B是空间中的全部事件,因此Collectively exhaustive也正确
c不确定,a和b好像对的,那就选d吧
