The expected return of the stock is the return that can be expected to be earned given the three states of the economy.
Expected return = (probability of a boom x return in a boom) + (probability of a normal economy x return in a normal economy) + (probability of a recession x return in a recession)
probability of a recession = 100 - 16 - 68 = 16%
Expected return = (22% x 0.16) + (11% x 0.68) - (8% x 0.16) = 9.72%
