Answer 1

Answer:

A positive value of Covariance means that two random variables tend to vary in the same direction, a negative value means that they vary in opposite directions, and a 0 means that they don't vary together. ... Recall that X and Y are random variables, while E(X) and E(Y) are averages and thus are constants
