The probability that A hits a target is 1/3 and the probability that B hits it, is 2/5. What is the probability that the target will be hit, if each one of A and B shoots at the target?
Given,
Probability that A hits a target is 1/3
P(A)=
The probability that B hits it, is 2/5
P(b)=
P(target will be hit)=1–P(target will not be hit)
=1–P(neither A nor B hit the target)
