10 percent of workers (16 years and over) in the U.S commute to their jobs by carpooling. Randomly select 20 workers. A) What is the probability that 8 workers in the sample carpool? B) In the sample of 20, how many would you expect to carpool?

Transportation Out of 80 workers surveyed at a company, 17 walk to work. a. What is the experimental probability that a randomly selected worker at that company walks to work? b. Predict about how many of the 360 workers at the company walk to work.
Data Analysis and Probability
Theoretical and Experimental Probability
According to the U.S. Census Bureau, the probability that a randomly selected worker primarily drives a car to work is $0.867 .$ The probability that a randomly selected worker primarily takes public transportation to work is 0.048 . (a) What is the probability that a randomly selected worker primarily drives a car or takes public transportation to Work? (b) What is the probability that a randomly selected worker neither drives a car nor takes public transportation to Work? (c) What is the probability that a randomly selected worker does not drive a car to work? (d) Can the probability that a randomly selected worker walks to work equal $0.15 ?$ Why or why not?
