If a point is randomly located in an interval (a, b) and if X denotes its distance from a, then X will be assumed to have a uniform distribution over (0, b - a). A plant efficiency expert randomly picks a spot along a 500-foot assembly line from which to observe work habits. Find the probability that she is
a Within 25 feet of the end of the line.
