With a terrain and make of concrete, experience from national highways suggests that there are, on the average, 2 potholes per mile after a certain amount of usage. We wish to know how likely it is to find no more than one pothole in a section of 5 miles of a highway. What is the most appropriate probability distribution to describe the random variable of interest? What is the average number of potholes in a section of 5 miles of a certain highway?
