Q2: The number of cracks in a section of interstate highway that are significant enough to require repair is assumed to follow a Poisson distribution with a mean of 3 cracks per mile. What is the probability that is at least four crack requires repair in 3 miles of highway? a) What is the probability that there are no cracks that require repair in 4 miles of highway? b) What is the probability that is at least one crack requires repair in 0.5 mile of highway? c) What is the probability that is at least four crack requires repair in 3 miles of highway?
