The following practice problem has been generated for you:
Asset 1 makes up 39% of a portfolio and has an expected return (mean) of 18% and volatility (standard deviation) of 10%.
Asset 2 makes up 61% of a portfolio has an expected return (mean) of 23% and volatility (standard deviation) of 15%.
With a covariance of 12%, calculate the expected return, variance, and standard deviation of the portfolio
