Generalisation. The mathematical expectation of the product of a number of independent random variables is equal to the product of their expectations. Symbolically, if X1, X, . X, are n independent r.v.'s, then E (X1, X2, ... X,) E (X1) E (X2) ... E (X„) E I x.) = I E (X), i.e., i = 1 provided all the expectations exist.
