The probability of hitting a target by three marksmen are 1/2,1/3 and 1/4. Then find the probabiglity that one and only one of them will hit the target when they fire simultaneously.

The probability of hitting a target by three marksmen are 1/2, 1/3 and 1/4. Then find the probability that no one will hit the target when they fire simultaneously.

The probability of A hitting a target is 4/5 and that of B hitting it is 2/3 . They both fire at the target . Find the probability that : only one of them will hit the target.

A is targeting to B, B and C are targeting to A. probability of hitting the target by A, B and C are 2/3, 1/2 and 1/3, respectively. If A is hit, then find the Probability that B hits the target and C does not.

The probability of hitting a target in any shot is 0.2.If 10 shots are fired,find the probability that the target will be hit atleast twice.
