Solution

## The correct option is A 12This is a question of conditional probability, the condition being given here that the selected person is a female.Since the selected person is a female, the sample space becomes 6 since there were 6 females in total.Next, out of those 6 only 3 females are above 40 years of age and so the probability that the selected female is aged above 40 becomes 36=12
