Requirement 1: If you bought an equally weighted portfolio of Tesla, Target, and Toyota shares, what return would you expect to receive every year on your stock investment? (Do not round your intermediate calculations.) Requirement 2: What do you expect the variance of your portfolio returns to be, if you invested 10 percent of your money in Tesla's shares, same proportion in Target's shares, and 80 percent in Toyota's shares? (Do not round your intermediate calculations.)
