Question

According to a survey, the probability that a randomly selected worker primarily drives a bicycle to work is 0.857. The probability that a randomly selected worker primarily takes public transportation to work is 0.063. Complete parts (a) through (d) () 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 or takes pubilie transportation to work? Plworkernelther 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 the decimal places as needed)

Answer 1

P(Bicycle) = 0.857

P(Public transport) = 0.063

a) P(worker drives a bicycle or takes public transportation to work) = 0.857 + 0.063 = 0.92

b) P(worker neither drives a bicycle nor takes public transportation to work) = 1 - 0.92 = 0.08

c) P(worker does not drive a bicycle to work) = 1-0.857 = 0.143

d) Answer A: No, The probability a worker primarily drives, walks, or takes public transportation would be greater than 1.
