WebChebyshev’s inequality tells us that the probability of X X falling more than k k standard deviations from its mean (in either direction) is at most 1/k2 1 / k 2. The power of Chebyshev’s inequality is that it is widely applicable – it only requires that X X have finite mean and variance. Webwhich gives the Markov’s inequality for a>0 as.
