Suppose that 30% of students are freshmen, 60% own a car, and 10% are freshman and own a car. If a student is selected a random, what is the probability that the selected student will be a freshman or own a car (or both)?
------------------------
P(f or c) = P(f) + P(c) - P(f and c)
P(f or c) = 0.30 + 0.60 - 0.10 = 0.80
