Based on the following information, calculate the expected return and standard deviation and variance for two stocks:

This is what i have so far and i am stuck if someone can check my work so far and help me fill in the rest thanks

State of the Economy	Probability	Rate of Return Stock A	Rate of Return Stock B
Recession	.25	.05	-.19
Normal	.50	.06	.14
Boom	.25	.10	.34

Stock A	Probability	Return	Product	Return Deviation	Squared Deviation	Product
Recession	0.25	0.05	1.2500
Normal	0.50	0.06	3.0000
Boom	0.25	0.10	2.5000
		E(R) =	6.5000		Variance =	-
	Standard Deviation	1.92%
Stock B	Probability	Return	Product	Return Deviation	Squared Deviation	Product
Recession	0.25	(0.19)	(47.6188)
Normal	0.50	0.14	7.0000
Boom	0.25	0.34	85.0000
		E(R) =	10.7500		Variance =	-
