A is trying to break a bulb by throwing balls at it. If he hits the bulb 4 times in every 11 throws and bulb breaks 3 times out of 7 hits, then find the probability of A breaking the bulb.
Probability of A hitting the bulb = 4/11 Probability of the bulb being broke on getting hit = 3/7 Probability of A breaking the bulb = (4/11) × (3/7) = 12/77
