Up to 20% of people in the United States will catch the flu this year. Use this figure as the population mean, and assume you work in an office space with 30 coworkers: a. How many of your coworkers would you expect to get the flu this year? b. What's the standard deviation? c. Using the appropriate approximation, determine P(x> 1), that is, the probability that more than one of your coworkers will get the flu this year.
