Question
According to a survey, the probability that a randomly selected worker primarily drives a bicycle to work is 0.869
The probability that a randomly selected worker primarily takes public transportation to work is 0.041. 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
0.15?
Why or why not?Yes. The probability a worker primarily drives, walks, or takes public transportation would equal 1.
Yes. If a worker did not primarily drive or take public transportation, the only other method to arrive at work would be to walk.
No. The probability a worker primarily drives, walks, or takes public transportation would be greater than 1.
No. The probability a worker primarily drives, walks, or takes public transportation would be less than 1.
