A local paving company obtained a contract with the county to maintain roads serving a large urban center. The roads recently paved by this company revealed an average of two defects per mile after being used for one year. If the county retains this paving company, what is the probability of one defect in any five mile of road after carrying traffic for one year? Assume a Poisson distribution and use the formula. O 0.0045 0.0004 O 0.0027 0.0005
