i) What is the probability that the actualized return on security A will be equal or less than zero in the coming investment period?
ii) What is the probability of actually losing 5% or more on security M in the coming investment period?
Calculate the covariance between A and M.
Calculate the correlation coefficient between securities A and M. Verify that the covariance given in part (e) above is equal to the product of the standard deviation of A, standard deviation of M and the correlation coefficient between A and M.
