Question
The total cost to the insurer for an insurance claim is P = X + Y + 50, where X represents the claim amount and Y represents the expense amount. The variance of the total cost is 100, the standard deviation of X is three times the standard deviation of Y and the correlation coefficient of X and Y is 0.8. Calculate the covariance of X and Y. a 3.60 b 9.84 c 16.2 d 19.4 e 24.0
