Suppose `Aa n dB` shoot independently until each hits his target. They have probabilities 3/5 and 5/7 of hitting the targets at each shot. Find probability that `B` will require more shots than `Adot`

Suppose A and B shoot independently until each hits his target. They have probabilities 3/5 and 5/7 of hitting the target at each shot. The probability that B will require more shots than A is

Three persons A, B and C shoot to hit a target. Their probabilities of hitting the target are 5/6, 4/5 and 3/4 respectively. Find the probability that: Exactly two persons hit the target.

Three persons A , B and C shoot to hit a target. Their probabilities of hitting the target are 5/(6), 4/(5) and 3/(4) respectively. Find the probability that : Exactly two persons hit the target.

Three persons A , B and C shoot to hit a target. Their probabilities of hitting the target are 5/(6), 4/(5) and 3/(4) respectively. Find the probability that : At least one person hit the target.

Three persons P, Q and R independentlytry to hit a target. If the probabilities oftheir hitting the target are 3/4,1/2 and 5/8 respectively, then the probability that thetarget is hit by P or Q but not by R is:

On average, a sharpshooter hits the target once every 3 shots. What is the probability that he will hit the target in 4 shots?

The probability of a man hitting a target is 0.25. He shoots 7 times. What is the probability of his hitting at least twice?

The probability of a man hitting a target is 0.25. He shoots 7 times. What is the probability of his hitting at least twice?

Three persons A, B and C shoot to hit a target. Their probabilities of hitting the target are (5)/(6),(4)/(5) and (3)/(4) respectively. Find the probability that: (i) Exactly two persons hit the target. (ii) At least one person hits the target.

The probability that a man can hit a target is 3//4 . He tries 5 times. The probability that he will hit the target at least three times is
