That is, the … Web14 jun. 2005 · THanks in advance. For a random variable X, the variance is defined as: Var (X) = E [ (X-E [X])^2]. Thus, Var (X) = E [ (X^2 - 2XE [X] - (E [X])^2]. Remember that the expected value of a constant, say a, is this constant: E (a) = a, where a is a constant. And also that: E [ E [X] ] = E [X]. Then, we have that:
