Three persons A,B and C fire a target in turn . Their probabilities of hitting the target are `0.4 , 0.3 and 0.2 ` respectively . The probability of two hits is

Three persons A,B and C, fire at a target in turn, starting with A. Their probability of hitting the target are 0.4, 0.3 and 0.2, respectively. The probability of two hits 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 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.

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:

3 firemen X, Y and Z shoot at a common target. The probabilities that X and Y can hit the target are 2/3 and 3/4 respectively. If the probability that exactly two bullets are found on the target is 11/24 then find the probability of Z to hit the target.

Two aeroplanes I and II bomb a target in succession. The probabilities of I and II scoring a hit correctly are 0.3 and 0.2, respectively. The second plane will bomb only if the first misses the target. The probability that the target is hit by the second plane is (A) 0.06 (B) 0.14 (C) 7/22 (D) 0.7

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.

An anti aircraft gun take four shots at an enemy plane moving away from it. The probability of hitting the plane at the first, second, third and fourth shot are 0.4, 0.3, 0.2 and 0.1 respectively. The probability that the gun hit the plane is :- (A) 0.25 (B) 0.21 (C) 0.16 (D) 0.6976
