A person is known to hit the target in 3 out of 4 shots,where as an other person is known to hit twice ineverythree attempts. If both of themtry independently the probability that the target being hit is

A and B try to hit a target. The probability that A hits the target is 7/10 and the probability that B hits the target is 4/10. If these two events are independent, the probability that B hits the target, given that the target is hit,is :

A can hit a target 3 xx in 6 shots; B,2 xx in 4 shots and C,4 xx in 4 shots.All of them fire at a target independently.The probability that the target will be hit is

A can hit a target in 3 out of 4 shots and B can hit the target in 4 out of 5 shots. What is the probability of hitting the target ?

A hits the target 4 out of 5 times, B hits the target 3 out of 4 times and C hits the target 2 out of 3 times, then the probability of hitting by exactly one person is

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.

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 independently, then the probability that the target would be hit, is

The probability of A hitting a target is (4)/(5) the probability of B hitting the target is (3)/(4) and the probability of C missing the target is (1)/(3) .What is the probability of the target being hit at least twice.

The probability that a person will hit a target in shooting practice is 0.3. If he shoots 10 times, the probability that he hits the target is
