Question

Let's consider the annual precipitation levels in Los Angeles county. Suppose the average annual precipitation in LA county is normally distributed with a mean of 15 inches and a standard deviation of 3 inches.

We can classify the precipitation levels in the following way:

*Dry*	Annual precipitation is more than 1 standard deviation below the mean.
*Normal*	Annual precipitation is less than 1 standard deviations below the mean and less than 2 standard deviation above the mean.
*Humid*	Annual precipitation is more than 2 standard deviations above the mean.

Before answering the following questions it may be helpful to mark on a bell shaped curve where the above regions lie.

According to the empirical rule, what is the probability of experiencing a Dry year in Los Angeles?
According to the empirical rule, what is the probability of experiencing a Humid year in Los Angeles?
According to the empirical rule, what is the probability of experiencing a Normal year in Los Angeles?
