    B) 2/5

    C) 3/5

    D) None of these

    Correct Answer: A

    Solution :

    [a] Let P[a] = Probability that a randomly selected student likes chocolate = 0.5 Let \[P(B)=\]Probability that a randomly selected students likes cake = 0.3 Then \[P(A\cap B)=0.1\] Now we have to find \[P(A/B)=P(A\cap B)/P(B)=0.1/0.3=1/3\]
