6. Alvie, a marksman, fires seven independent shots at a target. Suppose that the probabilities that he hits the bull’s-eye, he hits the target but not the bull’s-eye, and he misses the target are 0.4, 0.35, and 0.25, respectively. What is the probability that he hits the bull’s-eye three times, the target but not the bull’s-eye two times, and misses the target two times?
