Hello
I'm unable to recall the formula used here for calculating the covariance . This is the solution of Question 1.2(i) from chapter 1 practice questions ( on page 29)

These are the covariance formulae used in NTU's CT6 and CT4, respectively.

Can you please explain how have we used these formulas in solving the above problem?
