Probability of hitting a targen independently of 4 persons are `(1)/(2),(1)/(3),(1)/(4),(1)/(8)`. Then the probability that target is hit is-

Four persons can hit a target correctly with probabilities (1)/(2),(1)/(3),(1)/(4) and (1)/(8) respectively. Probability that target is hit if all hit at the target at same time

A, B, C try to hit a target simultaneously but independently. Their respective probabilities of hitting the target are (3)/(4),(1)/(2),(5)/(8) . The probability that target is hit by A or B but not C is

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