Average Precipitation For the first 7 months of the year, the average precipitation in Toledo, Ohio, is 19.32 inches. If the average precipitation is normally distributed with a standard deviation of 2.44 inches, find these probabilities.

a. A randomly selected year will have precipitation greater than 18 inches for the first 7 months.

b. Five randomly selected years will have an average precipitation greater than 18 inches for the first 7 months.
