Four persons can hit a target correctly with probabilities (1)/(2),(1)/(3),(1)/(4) and (1)/(8) respectively. If all hit at the target would be 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

Three persons hit a target with probabilities (1/2) , (1/3) and (1/4) respectively. If each one shoots at the target once, (i) find the probaility that exactly one of them hits the target, (ii) if only one of them hits the target what is the probability that it was the first person?

Three persons hit a target with probability 1/2,1/3 and 1/4 respectively. If each one shoot at the target once, if only one of them hits the target what is the probability that it was the first person ?
