Question

A can hit a target 4 times in 5 shots, b can hit 3 times in 4 shots, and C can hit 2 times in 3 shots. Calculate the probability that
(i) A, B and C all hit the target
(ii) B and C hit and A does not hit the target.

Answer 1

Correct Answer - (i) `2/5` (ii) `1/10`
`P("A hits")=4/5, P("B hits")=3/4` and `P("C hits")=2/3`.
(i) P (A hits and B hits and C hits) `=P(A)xxP(B)xxP(C)`.
(ii) P (B hits and C hits and A does not hit)
`=P(B)xxP(C)xxP(bar(A))`.
