The probability that Kofi and Ama hit a target in a shooting...

The probability that Kofi and Ama hit a target in a shooting competition are 16 and 19 respectively. What is the probability that only one of them hit the target?

A.

154

B.

1354

C.

2027

D.

4154

Correct answer is B

P(only one hit target) = P(Kofi not Ama) + P(Ama not Kofi)

P(Kofi not Ama) = P(Kofi and Ama') = 16×89=854

P(Ama not Kofi) = P(Ama and Kofi') = 19×56=554

P(only one hit target) = 854+554=1354
