The Central Limit Theorem for Sample Means (Averages) Suppose X is a random variable with a distribution that may be known or unknown (it can be any distribution). If you draw random samples of size n, then as n increases, the random variable [latex]\displaystyle\overline{{X}}[/latex].
The expected value of the function g(X,Y) of two discrete random variables, with joint probability mass function pX,Y(x,y), is denoted by E[g(X,Y)] and is calculated as. This definition can be extended to three or more discrete random variables. In general, if a set of random variables X1 , X2, ....
