Answer:

Variance of the return = 0.01983

Explanation:

[tex]S^{2}[/tex]= Σ[tex](X-X)^{2}[/tex]/ N - 1

Mean return = 17.88% + -5.16% + 20.39% = 11.0367%  

Variance = [(17.88% - 11.0367%)2 + (-5.16% - 11.0367%)2 + (20.39% - 11.0367%)2] /(3 - 1)

Variance = [0.004683 + 0.026233 + 0.008748]/2

Variance = 0.01983
