Given the returns and probabilities for the three possible states listed below, calculate the covariance between the returns of Stock A and Stock B. For convenience, assume that the expected returns of Stock A and Stock B are 10.00 percent and 16.00 percent, respectively. (Round answer to 4 decimal places, e.g. 0.0768.) Probability Return on Stock A Return on Stock B Good 0.35 0.30 0.50 OK 0.45 0.10 0.10 Poor 0.20 -0.25 -0.30 Covariance
