Question
A is trying to break a bulb by throwing balls at it. If
he hits the bulb 4 times in every 9 throws and bulb breaks 3 times out of 12 hits, then find the probability of A breaking the bulb.Solution
Probability of A hitting the bulb = 4/9 Probability of the bulb being broke on getting hit = 3/12 = 1/4 Probability of A breaking the bulb = (4/9) × (1/4) = 1/9
