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. WebThe prime number theorem is an asymptotic result. It gives an ineffective bound on π(x) as a direct consequence of the definition of the limit: for all ε > 0, there is an S such that for all x > S , However, better bounds on π(x) are known, for instance Pierre Dusart 's.
