Answer:
Explanation:
Expected return of the portfolio is weighted average of the return of the components.
E(R) = w1 * R1 + w2 * R2
E(R) = 65% * 18% + 35% * 6%
E(R) = 11.70% + 2.10%
Expected Return, E(R) = 13.80%
Standard deviation of portfolio is mathematically represented as:

where
w1 = the proportion of the portfolio invested in Asset 1
w2 = the proportion of the portfolio invested in Asset 2
σ1 = Asset 1 standard deviation of return
σ2 = Asset 2 standard deviation of return
For risk free money market fund, standard deviation = 0 and its correlation with risky portfolio = 0

Standard deviation = 19.50%
