Suppose a portfolio has an average annual return of 11.5% (i.e. an average gain of 11.5%) with a standard deviation of 38.5%. A return of 0% means the value of the portfolio doesnt change, a negative return means that the portfolio loses money, and a positive return means that the portfolio gains money. (a) What percent of years does this portfolio lose money, i.e. have a return less than 0%? (b) What percent of years does this portfolio return more than 15%?
