Question

Person a and person b shoot to the same target independently. person a hits the target with a probability of 0.8, while person b hits the target with a probability of 0.9. what is the probability that the target can be hit?

Answer 1

P(A∪B) = P(A) + P(B) - P(A∩B) = 0.8 + 0.9 - 0.8×0.9

= 1.70 - 0.72 = 0.98

The probability the target will be hit is 0.98.
