Stay in school: In a recent school year in the state of Washington, there were 321,000 high school students. Of these, 154,000 were girls and 167,000 wereboys. Among the girls, 57,500 dropped out of school, and among the boys, 10,300 dropped out. A student is chosen at random. Round the answers to fourdecimal 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 student is male and dropped out?(d) Given that the student is male, what is the probability that he dropped out?(e) Given that the student dropped out, what is the probability that the student is male?

WINDO In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 208 answered "none," 285 said "one," 361 said "two," 140 said "three," and 56 responded with four or more. A survey respondent is selected at random.
