A can hit the target 3 times in 6 shots,B 2 times in 6 shots and C 4times in 6 shots.They fire a volley . What is the probability that at least 2 shots hit?

• P(A) = 3/6=1/2;; P(B) = 2/6=1/3;; P(C) = 4/6=2/3;; P(A')= 3/6=1/2;; P(B') = 4/6=2/3;; P(C') =2/6=1/3;; AT LEAST TWO SHOTS HIT PROBABILITY IS ;; P(ABC')+P(BCA')+P(CAB')+ P(ABC)= (1/2 * 1/3 *1/3)+ (1/3*2/3*1/2)+(2/3*1/2*2/3)+(1/2*1/3*2/3);; = 1/18+2/18+4/18+2/18= 9/18= 1/2;; THIS MEANS THE PROBABILTY OF HITTING IS 1TIME IN TWO SHOTS
