Chebyshev’s inequality does not hold for k
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.

WebChebyshev’s Inequality gives an upper bound to the probability that the absolute deviation of a random variable from the mean will exceed a stated amount. The formula reads as … Chebyshev's inequality is more general, stating that a minimum of just 75% of values must lie within two standard deviations of the mean and 88.89% within three standard deviations for a broad range of different probability distributions. See more In probability theory, Chebyshev's inequality (also called the Bienaymé–Chebyshev inequality) guarantees that, for a wide class of probability distributions, no more than a certain fraction of … See more Suppose we randomly select a journal article from a source with an average of 1000 words per article, with a standard deviation of 200 … See more Markov's inequality states that for any real-valued random variable Y and any positive number a, we have Pr( Y ≥a) ≤ E( Y )/a. One way to prove Chebyshev's inequality is to apply Markov's inequality to the random variable Y = (X − μ) with a = (kσ) : See more The theorem is named after Russian mathematician Pafnuty Chebyshev, although it was first formulated by his friend and colleague See more Chebyshev's inequality is usually stated for random variables, but can be generalized to a statement about measure spaces.
