2. We have two random variables representing returns on two assets: X₁ and X₂. They have the following covariance matrix: 0.01 -0.01] Ex = [ -0.01 0.04 Now we create three new portfolios with the following returns: Y₁ = 0.25X₁ +0.75.X2 Y₂ = 0.5X₁ +0.5X2 Y3aX₁ + (1 - a) X₂ a. Find a such that Y2 and Y3 are uncorrelated. b. Suppose a = 0.75. Find the correlation matrix of Y₁, Y2 and Y3. Note: For b, you should set up the problem by hand but it is much easier to solve computationally. If you do that, include your code in the solution.
