问题如下:
Based on the probabilities in the diagram below, what is the value of the following?
Pr(A∪B|C)
选项:
A.
10%
B.
81.1%
C.
53%
D.
18.9%
解释:
Pr(A∪B|C) = Pr((A∪B)∩C)/Pr(C) = (15% + 10% + 18%)/53% = 81.1%
在c发生的情况下a和b的交集,图上看应该是10%

NO.PZ2020010301000016问题如下 Baseon the probabilities in the agrbelow, whis the value of the following?Pr(A∪B|A.10%B.81.1%C.53%18.9%Pr(A∪B|= Pr((A∪B)∩C)/Pr(= (15% + 10% + 18%)/53% = 81.1%为什么是/C发生的概率,而不是*C发生的概率?
NO.PZ2020010301000016 81.1% 53% 18.9% Pr(A∪B|= Pr((A∪B)∩C)/Pr(= (15% + 10% + 18%)/53% = 81.1% 公式跟书上也不一样。
请问一下,这个不是说在C事件发生的情况下,A并B的概率吗?
