ACCORDING TO THE : PROPERTIES OF MATHEMATICAL EXPECTATION E(Ctimes X)= (C=constant) Select one: =C =Ctimes E(X) =C^2times E(X) =1 =Ctimes X

The correct answer is: Explanation: The mathematical expectation of a constant multiplied by a random variable is equal to the constant multiplied by the mathematical expectation of the random variable. In this case, is a constant and is a random variable. Therefore, .
