Consider the following distribution of returns:

3.1 Please calculate the expected return and volatility for each of the three stocks. Your answer should include 6 numbers: R_a, R_b, R_c, _a, _b, _c.

3.2 Based on the distribution above compute the covariance between A and B. Round off your final answer to two digits after the decimal point (such as 5.55, omit percentage %)

3.3 Calculate the correlation coefficient between A and B. Round off your final answer to two digits after the decimal point (such as 5.55). (Hint: Your answers to previous questions may be useful.)

3.4 What would be the expected return and standard deviation of a portfolio with 60% in A and 40% in B?
