5. The following represents the probability distribution for the rates of return for next month:

Probability	Portfolio "P"	Market "M"
1/6	-20%	-5%
1/6	-5%	5%
1/2	10%	0%
1/6	50%	10%

Compute by hand (and show your work) for the following questions.

a. (5 points) Find the risks (standard deviations) and rewards (expected rates of return) of P and of M (do each one separately).

b. (4 points) Find the covariance of M and P

c. (1 point) Find the market beta of P.

d. (1 point) If you were to hold a portfolio with one quarter of your funds invested in P and the rest invested in M, what would be the beta of this portfolio?
