In a class, 40% of the students study math and science. 60% of the students study math. What is the probability of a student studying science given he/she is already studying math?
Answer with explanationAnswer: Option D
P(M and S) = 0.40
P(M) = 0.60
P(S|M) = P(M and S)/P(S) = 0.40/0.60 = 2/3 = 0.67
