Problem $13-31$ Using CAPM $($LO$1,4)$

There are two stocks in the market, stock A and stock B$.$ The price of stock A today is $$76.$ The price of stock A next year will be $$64$ if the economy is in a recession, $$84$ if the economy is normal, and $$96$ if the economy is expanding. The probabilities of recession, normal times, and expansion are $0\mathrm{.}2,0\mathrm{.}6,$ and $0\mathrm{.}2,$ respectively. Stock A pays no dividends and has a beta of $0\mathrm{.}79.$ Stock B has an expected return of $13\%,$ a standard deviation of $34\%,$ a beta of $0\mathrm{.}56,$ and a correlation with stock A of $0\mathrm{.}48.$ The market portfolio has a standard deviation of $14\%.$ Assume the CAPM holds.
