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 0.13 and 0.19, respectively. (Round your answer to 4 decimal places. For example .1244)

Probability	Return(A)	Return(B)
Good	0.35	0.30	0.50
OK	0.50	0.10	0.10
Poor	0.15	-0.25	-0.30
