    he hits the bulb 3 times in every 12 throws and bulb breaks 3 times out of 18 hits, then find the probability of A breaking the bulb.
    A 1/14 Correct Answer Incorrect Answer
    B 1/20 Correct Answer Incorrect Answer
    C 1/24 Correct Answer Incorrect Answer
    D 1/26 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Probability of A hitting the bulb = 3/12 = 1/4 Probability of the bulb being broke on getting hit = 3/18 = 1/6 Probability of A breaking the bulb = (1/4) × (1/6) = 1/24
