A. 0.4
B. 0.2
C. 0.6
D. 0.45
Answer: Option A
Solution (By Examveda Team)
Given Data:The question asks for the probability that a pink-wearing guest is a man. Therefore, we consider only the guests who are wearing pink.
There are 50 pink-wearing guests, out of whom 20 are men.
Conditional Probability:
P(Man | Pink) = Number of Pink-wearing Men / Total Number of Pink-wearing Guests
= 20 / 50
= 0.4
Therefore, the probability that a pink-wearing guest is a man is 0.4.
Hence, the correct answer is Option A: 0.4.
