Question
A is trying to break a bulb by throwing balls at it. If he hits the bulb 4 times in every 10 throws and bulb breaks 3 times out of 20 hits, then find the probability of A breaking the bulb.
Solution
Probability of A hitting the bulb = 4/10 = 2/5 Probability of the bulb being broke on getting hit = 3/20 Probability of A breaking the bulb = (2/5) × (3/20) = 3/50
