Probability Question 160
Question: If the events A and B are mutually exclusive, then $ P( \frac{A}{B} )= $
Options:
A) 0
B) 1
C) $ \frac{P(A\cap B)}{P(A)} $
D) $ \frac{P(A\cap B)}{P(B)} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ P( \frac{A}{B} )=\frac{P(A\cap B)}{P(B)} $
Since $ A $ and $ B $ are mutually exclusive. So, $ P(A\cap B)=0 $ .
Hence $ P( \frac{A}{B} )=\frac{0}{P(B)}=0 $ .
