You can put this solution on YOUR website! You are conducting a survey at a college with 800 students, 50 faculty members, and a 150 administrative staff members. Each of these 1000 individuals has a single listing in the campus phone directory. Suppose you were to cut up the directory and pull out one listing at random to contact. What is the probability it would be
(a) P(a student) = 800/1000
(b) P(a faculty member) = 50/1000
And so forth.
