Stay in school: In a recent school year in the state of Washington, there were 320,000 high school students. Of these, 154,000 were girls and 166,000 were boys. Among the girls, 39,000 dropped out of school, and among the boys, 10,300 dropped out. A student is chosen at random. Round the answers to four decimal places.(a) What is the probability that the student is male?(b) What is the probability that the student dropped out?(c) What is the probability that the...
