WebOct 11, 2004 · Cherno gives a much stronger bound on the probability of deviation than Chebyshev. This is because Chebyshev only uses pairwise independence between the r.v.s whereas Cherno uses full independence. Full independence can some times imply exponentially better bounds. 9.5.2 Coloring a hypergraph Consider the following problem.

It states that a random variable with finite variance is concentrated around its expectation. The smaller the variance, the stronger the concentration. Both inequalities are used to claim that most of the time, random variables don't get "unexpected" values. husqvarna chainsaw rancher 55 manual
