The expected possible outcomes for Roxy Stock are below. What is the expected return? What is the expected variance? What is the expected standard deviation?

Outcome	Probability	Return
Recession	40%	-25%
Expansion	25%	20%
Boom	35%	45%

Here is what I am getting - I think there is a disconnect with my totals. Can you please point me in the right direction?

Outcome		Return (Re)	Probability(P)	Expected Return (Er)	Re-Er	(Re-Er)2	P x (Re-Er)2 = this will give you Variance number
Recession		-0.25	0.4	(-25x.4)= -0.1	(-.25-(-.1)) = .35	(.35)2 =.1225	(0.4) x (.1225) = 0.049
Expansion		0.2	0.25	(0.2x.25)= .05	(.2-.05) = .15	(.15)2 = .0225	(.25) x (.0225) = 0.005625
Boom		0.45	0.35	(.45x.35)= .1575	(.45-.1575) = .2925	(.2925)2 = .0856	(.35) x (.0856) = 0.02996
Total				10.75%		Variance =	.084585 or 8.46%
						Standard Deviation = Square Root of Variance = 29.08%
