Consider the following information:

Rate of Return if State Occurs

State of Economy Probability of State of Economy Stock A Stock B

Recession $0\mathrm{.}150\mathrm{.}070\mathrm{.}20$

Normal $0\mathrm{.}550\mathrm{.}120\mathrm{.}15$

Boom $0\mathrm{.}300\mathrm{.}200\mathrm{.}30$

Calculate the expected return for each stock. $($Do not round intermediate calculations. Round the final answers to $2$ decimal places.$)$
