Question
A can hit a target 4 times in 5 shots, B 3 times in 4 shots, and C 2 times in 3 shots. Calculate the probability that
(i) A B, C all may hit (ii) B, C may hit and A may lose.
Solution
Let E1 , E2 , E3 be the events ‘A hits a shot’, ‘B hits a shot,’ ‘C hits a shot’ respectively.
(i) P(A, B, C all may hit) =
(ii) P(B, C may hit and A may lose)
(i) P(A, B, C all may hit) =
(ii) P(B, C may hit and A may lose)
