?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.
