29.Consider G1, G2 and G3 denote the events that the target hits by the first, second and third guns respectively. If P(G1) = 0.5, P(G2) = 0.6 and P(G3) = 0.8 and G1, G2 and G3 are independent of each other. Then what is probability of registering exactly one hit? (a) 0.22 (b) 0.24 (c) 0.26 (d) 0.28 (e) 0.30
