You are considering the risk-return profile of two mutual funds for investment. The relatively risky fund promises an expected return of 12.5% with a standard deviation of 19.2%. The relatively less risky fund promises an expected return and standard deviation of 4.1% and 5.9%, respectively. Assume that the returns are approximately normally distributed. a-1. Calculate the probability of earning a negative return for each fund. Note: Do not round intermediate calculations. Round your final answers to 4 decimal places. a-2.
