(a) What is the probability that a randomly selected worker primarily drives a van or takes public transportation to work? P(worker drives a van or takes public transportation to work) = (Type an integer or decimal rounded to three decimal places as needed.) (b) What is the probability that a randomly selected worker primarily neither drives a van nor takes public transportation to work? P(worker neither drives a van nor takes public transportation to work) = (Type an integer or decimal rounded to three decimal places as needed.) (c) What is the probability that a randomly selected worker primarily does not drive a van to work? P(worker does not drive a van to work) = (Type an integer or decimal rounded to three decimal places as needed.) (d) Can the probability that a randomly selected worker primarily walks to work equal 0.25? Why or why not? A. No. The probability a worker primarily drives, walks, or takes public transportation would be greater than 1. B. Yes. The probability a worker primarily drives, walks, or takes public transportation would equal 1. OC. No. The probability a worker primarily drives, walks, or takes public transportation would be less than 1. OD. Yes. If a worker did not primarily drive or take public transportation, the only other method to arrive at work would be to walk.
