Generalisation. The mathematical expectation of the sum of n random variables is equal to the suni of their expectations, provided all the expectations exist. Symbolically, if X1, X2, ., X, are random variables them E (X1 + X2+ ... + X,) = E (X1) + E (X2) + + E (X,) 11 E(E x = 2 E (X), if all the expectations exist. E E (X;), if all the expectations exist. i = 1 %3D or i = 1
