Question: Let X be the random variable of Exercise 2. (a) Calculate the function f(x) = P (|X 10| x). (b) Now graph the function f(x),

Let X be the random variable of Exercise 2.
(a) Calculate the function f(x) = P (|X − 10| ≥ x).
(b) Now graph the function f(x), and on the same axes, graph the Chebyshev function g(x) = 100/(3x2). Show that f(x) ≤ g(x) for all x > 0, but that g(x) is not a very good approximation for f(x).
