Suppose we have three portfolios, plus a risk-free asset that pays an expected return of 3% per year with a standard deviation of zero. a offers an expected return of 15% per year, with a standard deviation of 30% per year. b offers an expected return of 10% per year, with a standard deviation of 20% per year. c offers an expected return of 5% per year, with a standard deviation of 10% per year. suppose that a client asks you to choose a portfolio with an expected return of 39% per year, and as low a standard deviation as possible. which of a, b, and c do you include in the client's portfolio? why? what standard deviation can you achieve?

Adam drew two same size rectangles and divided them into the same number of equal parts. he shaded 1/3 of one rectangle and 1/4 of the other rectangle. what is the least number of parts into which both rectangles could be divided into?
