Question
![According to a survey, the probability that a randomly selected worker primarily drives a bicycle to work is 0.733. The probability that a randomly selected worker primarily takes public transportation to work is 0.096. Complete parts (a) through (d).
**(a)** What is the probability that a randomly selected worker primarily drives a bicycle or takes public transportation to work?
P(worker drives a bicycle 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 bicycle nor takes public transportation to work?
P(worker neither drives a bicycle 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 bicycle to work?
P(worker does not drive a bicycle 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 0.30? Why or why not?
- A. Yes. The probability a worker primarily drives, walks, or takes public transportation would equal 1.
- B. Yes. If a worker did not primarily drive or take public transportation, the only other method to arrive at work would be to walk.
- C. No. The probability a worker primarily drives, walks, or takes public transportation would be less than 1.
- D. No. The probability a worker primarily drives, walks, or takes public transportation would be greater than 1.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa2a79f3c-9d5f-475d-8512-37c872933c1c%2Fc4eb596c-6525-4c45-9846-fadeffaf44ff%2Fzwpm33j.png&w=3840&q=75)
