Probability and Events

Question

A survey of students in a class of  32 students found that 15 students are boys, 18 students participate in clubs, and  6 students both are boys and participate in clubs. 

What is the probability that a student participates in clubs, given that the student is a boy?

answers:

6/32

2/5

5/2

Answer 1

Out of 15 boys, 6 are in a club, so the probability is 6/15, which reduces to 2/5.
