Web6.2.2 Markov and Chebyshev Inequalities. Let X be any positive continuous random variable, we can write. = a P ( X ≥ a). P ( X ≥ a) ≤ E X a, for any a > 0. We can prove the above inequality for discrete or mixed random variables similarly (using the generalized PDF), so we have the following result, called Markov's inequality . for any a > 0.
