Complete parts? (a) through? (d).

?(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)=____

?(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)=_____

?(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)=______

?(d) Can the probability that a randomly selected worker primarily walks to work equal 0.20?? Why or why? not?

A. Yes. The probability a worker primarily? drives, walks, or takes public transportation would equal 1.

B. No. The probability a worker primarily? drives, walks, or takes public transportation would be less than 1.

C. No. The probability a worker primarily? drives, walks, or takes public transportation would be greater than 1.

D. Yes. If a worker did not primarily drive or take public? transportation, the only other method to arrive at work would be to walk.
