Answer:
The risk premium on the risky investment is 8%
Explanation:
The first portfolio pays 15% rate of return with probability 60% in a good
The second portfolio 5% return with probability 40% in a bad state
The risk port-folio expected return = 60% * 15% + 40% * 5%
Expected return = 0.6 * 15% + 0.4* 5%
Expected return = 0.09 + 0.02
Expected return = 0.11
Expected return = 11%
Risk premium on the risky investment = Expected return - Risk free rate
= 11% - 5%
= 8%
The risk premium on the risky investment is 8%
