Question

    The probability that Dev clears the exam is (3/10) and the

    probability that Kriti fails is (1/6). What is the probability that both of them have the same result?
    A 11/30 Correct Answer Incorrect Answer
    B 13/30 Correct Answer Incorrect Answer
    C 3/10 Correct Answer Incorrect Answer
    D ½ Correct Answer Incorrect Answer
    E 17/30 Correct Answer Incorrect Answer

    Solution

    Probability that Dev fails = 1 - (3/10) = (7/10)
    Probability that Kriti passes = 1 - (1/6) = (5/6)
    Required probability = (3/10) × (5/6) + (7/10) × (1/6)
    = (15/60) + (7/60) = (22/60) = (11/30)
