Suppose the returns on an asset are normally distributed. The historical average annual return for the asset was 4.8 percent and the standard deviation was 14.3 percent.

What is the probability that your return on this asset will be less than 3.3 percent in a given year? Use the NORMDIST function in Excel to answer this question.

What range of returns would you expect to see 95 percent of the time?

What range of returns would you expect to see 99 percent of the time?
