Hi, I am having trouble understanding Chebychevs inequality.(adsbygoogle = window.adsbygoogle || []).push({});

when it states P[|x-mu|>=ksigma]<=1/k^2, I dont really get what x-mu represents, For example if I wanted to know the probability that a<x<b, how would I use the inequality?

would I have to put a and b in terms of standard deviations?, is that what x-mu represents?

Thank you so much, anything that you can say about the inequality, even if it doesnt answer my specific question may help me to understand it better...
