Q2) There is a 10.80% probability of an average economy and a 89.20% probability of an above average economy. You invest 38.10% of your money in Stock S and 61.90% of your money in Stock T. In an average economy the expected returns for Stock S and Stock T are 6.50% and 9.30%, respectively. In an above average economy the the expected returns for Stock S and T are 35.50% and 13.40%, respectively. What is the expected return for this two stock portfolio? (2 points)

I received the following solutions:

Stock S: E(R)= .357808

Stock T: E(R)= .129572

Portfolio E(R) = .103463

The correct answer was 20.35% or .2035

Please help me figure out where I went wrong.
