Suppose that in an automatic process of filling oil into cans, the content of can (in gallons) is Y = 50 + X, where X is a random variable with density f(x) = 1 – |x| when |x| ≤ 1 and 0 when |x| > 1. Graph f(x) and F(x). In a lot of 100 cans, about how many will contain 50 gallons or more? What is the probability that a can will contain less than 49.5 gallons? Less than 49 gallons?
