Q8 of 62 Page 1346

Mark (√) against the correct answer in each of the following:

A can hit a target 4 times in 5 shots, B can hot 3 times in 4 shots, and C can hit 2 times in 3 shots. The probability that B and C hit and A does not hit is


P(A) = P(B) = P(C) =


P(B CA’) = P(B C) – P(B CA)


As the events are independent, So, P(B C) = P(B).P(C) =


And P(B CA) = P(B).P(C).P(A) =


P(B CA’) =
