Task: Question Answering
Input (English): Suppose X and Y are random variables with E(X) = 37, var(X) = 5, E(Y) = 62, and var(Y) = 12. What are the expected value and variance of the random variable X + Y?
(A)E(X + Y) = 99, var(X + Y) = 8.5 (B)E(X + Y) = 99, var(X + Y) = 13 (C)E(X + Y) = 99, var(X + Y) = 17 (D)There is insufficient information to answer this question.
Output (English): D
