问题如下：
Based on the probabilities in the diagram below, what is the value of the following?
Pr(B|A∩C)
选项：
A. 15%
B. 30%
C. 10%
D. 40%
解释：
Pr(B|A∩C) = Pr(B∩A∩C)/Pr(A∩C) = 10%/(15% + 10%) = 40%
NO.PZ2020010301000014 30% 10% 40% Pr(B|A∩= Pr(B∩A∩C)/Pr(A∩= 10%/(15% + 10%) = 40% 下次遇到相同的表示，是一个含义吗？可否一下这个表示的意思？考试也是这么考嘛？
NO.PZ2020010301000014 如果是顺序变一下呢？p（a和c | 公式会怎样
NO.PZ2020010301000014 30% 10% 40% Pr(B|A∩= Pr(B∩A∩C)/Pr(A∩= 10%/(15% + 10%) = 40% 我觉得看图就是10%
30% 10% 40% Pr(B|A∩= Pr(B∩A∩C)/Pr(A∩= 10%/(15% + 10%) = 40%
