Answer:
The current portfolio has three stocks X, Y and Z and expected returns are are 6 percent, 19 percent, and 15 percent respectively.
Explanation:
The formula to calculate expected returns of the portfolio is:
Weighted return = Probability * Expected Return
The sum of weighted return is the expected return of the portfolio
Weighted return = (32% x 6% = 1.9%) + (20% x 19% = 3.8%) + (48% x 15% = 7.2%)
Expected return on portfolio = (1.9% + 3.8% + 7.2% = 12.9%)
The expected return of the portfolio is 12.9%
