1. Suppose you are given the following data. State Probability Market Return Security Return 1 0.1 -0.15 -0.30 2 0.3 0.05 0.00 3 0.4 0.15 0.20 4 0.2 0.20 0.50 (1) Compute the expected market return and the expected return on the security. (2) Compute the variances of the returns on the market and on the security. (3) Compute the covariance and the correlation coefficient between the market and the security. (4) Find expressions for the expected return and the variance of the return on a portfolio consisting of the market and the security
