he taxiways and runways of a major airport are carefully monitored to
expedite takeos and landing and to prevent collisions. If a pedestrian or vehicle enteres a radio-
controlled surface at an airport without receiving permission (control tower clearance), this is called a
deviation and incursion. In 2006, there were two serious deviations and incursions at the Los Angeles
International Airport. Suppose this is the mean number of deviations and incursions per year at LAX
and a random year is selected
