he hits the bulb 4 times in every 11 throws and bulb breaks 5 times out of 21 hits, then find the probability of A breaking the bulb.Solution
Probability of A hitting the bulb = 4/11 Probability of the bulb being broke on getting hit = 5/21 = 5/21 Probability of A breaking the bulb = (4/11) × (5/21) = 20/231
