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

The correct answer is: $=C\times E(X)$<br /><br />Explanation: The mathematical expectation of a constant times a random variable is equal to the constant times the mathematical expectation of the random variable. In this case, $C$ is a constant and $X$ is a random variable. Therefore, $E(C\times X) = C\times E(X)$.
