Explanation:
![\left[\begin{array}{cccc}State&Return&Probability&Weight\\recession&0.2&-0.116&-0.0232\\fail&0.8&0.165&0.132\\Total&&0.049&0.1088\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7DState%26Return%26Probability%26Weight%5C%5Crecession%260.2%26-0.116%26-0.0232%5C%5Cfail%260.8%260.165%260.132%5C%5CTotal%26%260.049%260.1088%5C%5C%5Cend%7Barray%7D%5Cright%5D)
The mean average return will be 0.1088
( (0.165 - 0.1088)² + (-0.116-0.1088)² ) / 2 =
( 0,00315844 + 0,05053504 ) / 2 = 0,02684674
Now, we calcualate the root:
²√0,02684674 = 0.163849748
