Suppose the returns on long-term government bonds are normally distributed. Assume long-term government bonds have a mean return of 5.7 percent and a standard deviation of 9.4 percent.

What is the probability that your return on these bonds will be less than −3.7 percent in a given year? Use the NORMDIST function in Excel® to answer this question. (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
