Asked by Adam

For traffic that flows on a highway, the headway is the average time between vehicles. On four-lane highways, the probability P (as a decimal) that the headway is at least t seconds when there are 500 vehicles per hour traveling one way is given is P = 0.87t Under these circumstances, what is the probability that the headway is at least 15 seconds? Round your answer to two decimal places.
