Chebyshev's Inequality : P(

Then a probability distribution of X is f(x) (pdf: probability density function) such that for any two numbers a and b, Conditions to be a legitimate probability distribution: f(x) ( 0, for all x (area under the entire graph of f(x)). If X is a continuous r.v., then for any number c, P(X=c)=0. Cumulative Distribution Function for X (cdf) : F(x) = ................
