n a CAPM world of only three risky securities (AAPL, MSFT, GOOG) and one risk-free asset (Rf), you want to construct a market portfolio (M) using AAPL, MSFT and GOOG with the following information provided.

	AAPL	MSFT	GOOG	Rf (the risk-free return)
Expected return	0.16	0.34	0.28	0.02
Standard deviation	0.23	0.23	0.21
Weights of the Market Portfolio (M)	- 0.13	0.69	0.44

Correlation matrix:

	AAPL	MSFT	GOOG
AAPL	1
MSFT	0.52	1
GOOG	0.42	0.65	1

Required: [Instruction: Do not round the intermediate answers, and round the final answers to two decimal places, e.g., 0.01]

a. Calculate the expected return and standard deviation of the market portfolio (M).

b. Calculate the covariance of AAPL with the market portfolio (M), that is, cov(AAPL, M).
