Question
Show that when $X$ and $Y$ are independent, $\operatorname{Cov}(X, Y)=\operatorname{Corr}(X, Y)=0$
Step 1
Step 1: The covariance of $X$ and $Y$ is defined as: \[ \operatorname{Cov}(X, Y) = E[(X-\mu_X)(Y-\mu_Y)] \] where $E$ is the expectation operator, and $\mu_X$ and $\mu_Y$ are the means of $X$ and $Y$ respectively. Show more…

Show that if X and Y are independent, then Cov(X, Y) = Corr(X, Y) = 0.
If $X$ and $Y$ are identically distributed, not necessarily independent, show that $$ \operatorname{Cov}(X+Y, X-Y)=0 $$
Properties Of Expectation
Theoretical Exercises
Suppose that random variables X and Y are defined on a sample space with only two elements. Suppose that Cov(X, Y ) = 0. Prove that X and Y are independent.
