The probability of A hitting a target is 1/3 and that of B is 1/5. If they fire together, what is the probability that the target is hit?
Q1. The probability of A hitting a target is 1/3 and that of B is 1/5. If they fire together, what is the probability that the target is hit?
Answer: 7 / 15
Explanation: P(at least one hits) = 1 - P(neither hits) = 1 - (2/3)*(4/5) = 7/15. Using complementary probability.
