    Question

    The probability that Aarav passes the exam is (3/8) and

    the probability that Meera fails the exam is (3/5). If both Aarav and Meera give the exam, then find the probability that both of them have the same result.
    A 21/40 Correct Answer Incorrect Answer
    B 19/40 Correct Answer Incorrect Answer
    C 17/40 Correct Answer Incorrect Answer
    D 23/40 Correct Answer Incorrect Answer

    Solution

    Probability that Aarav fails the exam = 1 - (3/8) = (5/8)
    Probability that Meera passes the exam = 1 - (3/5) = (2/5)
    Required probability = (3/8) × (2/5) + (5/8) × (3/5)
    = (6/40) + (15/40) = (21/40)
