Given the returns and probabilities for the three possible states listed here, 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 0.10and0.19, respectively. (Round your answer to 4 decimal places. For example .1244)

Probability Return(A) Return(B)

Good 0.35 0.3 0.5

OK 0.5 0.1 0.1

Poor 0.15 -0.25 -0.3
