Answer:
Variance  =0.008464
Explanation:
The probability that there will be recession = 100 – 80 = 20%
Therefore expected return =  Return × probability
                      =(0.8 × 14.3) + (0.2 × -8.7) Â
                      = 9.7%
Total probability is calculated in the table (use the attached table)
Standard deviation (SD) = [Total probability (84.64%)  × (Return (8.7%) - Expected Return (14.3%))^2 / Total probability (84.64%) ]^(1/2)
              =9.2%
Thus, variance  =  (SD)^2
      variance  =0.008464
