      A is trying to break a bulb by throwing balls at it. If

      he hits the bulb 3 times in every 5 throws and bulb breaks 3 times out of 12 hits, then find the probability of A breaking the bulb.
      A 5/20 Correct Answer Incorrect Answer
      B 3/10 Correct Answer Incorrect Answer
      C 3/20 Correct Answer Incorrect Answer
      D 5/21 Correct Answer Incorrect Answer

      Solution

      Probability of A hitting the bulb = 3/5 Probability of the bulb being broke on getting hit = 3/12 = 1/4 Probability of A breaking the bulb = (3/5) × (1/4) = 3/20
