Targets A and B are placed on a wall. It is known that for every shot the probabilities of hitting A and hitting B with a missile are, respectively, 0.3 and 0.4. If target A was not hit in an experiment, use simulation to calculate an approximate value for the probability that target B was hit. (The exact answer is 4/ 7. Hence the result of simulation should be close to 4/ 7 ≈ 0.571.)
