Stock A
Scenario	Probability	Return%	=rate of return% * probability	Actual return -expected return(A)%	(A)^2* probability
Bear	0.15	-3.2	-0.48	-13.745	0.002833875
Good	0.5	12.4	6.2	1.855	0.000172051
Bull	0.25	19.3	4.825	8.755	0.001916251

	Expected return %=	sum of weighted return =	10.55	Sum=Variance Stock A=	0.00492
			Standard deviation of Stock A%	=(Variance)^(1/2)	7.02

Stock B
Scenario	Probability	Return%	=rate of return% * probability	Actual return -expected return(A)%	(B)^2* probability
Bear	0.15	-10.3	-1.545	-19.23	0.005546894
Good	0.5	-2.5	-1.25	-11.43	0.006532245
Bull	0.25	46.9	11.725	37.97	0.036043023

	Expected return %=	sum of weighted return =	8.93	Sum=Variance Stock B=	0.04812
			Standard deviation of Stock B%	=(Variance)^(1/2)	21.94

Covariance Stock A Stock B:
Scenario	Probability	Actual return% -expected return% for A(A)	Actual return% -expected return% For B(B)	(A)(B)probability
Bear	0.15	-13.745	-19.23	0.003964745
Good	0.5	1.855	-11.43	-0.001060133
Bull	0.25	8.755	37.97	0.008310684

			Covariance=sum=	0.011215297
		Correlation A&B=	Covariance/(std devA*std devB)=	0.728718129
