Suppose the returns on an asset are normally distributed. The average annual return for the asset over some period was $6\mathrm{.}7$ percent and the standard deviation of this asset for that period was $9\mathrm{.}4$ percent. Based on this information, what is the approximate probability that your return on this asset will be less than $-3\mathrm{.}6$ percent in a given year?

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

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