WebMarkov’s & Chebyshev’s Inequalities Chebyshev’s Inequality - Example Lets use Chebyshev’s inequality to make a statement about the bounds for the probability of being with in 1, 2, or 3 standard deviations of the mean for all random variables. If we de ne a = k˙where ˙= p Var(X) then P(jX E(X)j k˙) Var(X) k2˙2 = 1 k2 WebChebyshev’s inequality gives a bound on the probability that X is far from it’s expected value. If we set a= k˙, where ˙is the standard deviation, then the inequality takes the form P(jX )j k˙) Var(X) k 2˙ = 1 k2: Example 6. Suppose a fair coin is ipped 100 times.
