The average lengths (from beak to tail) of different species of warblers in the eastern United States are approximately normally distributed with a mean of 12.9 centimeters and a standard deviation of 0.95 centimeter (see figure). The probability that a randomly selected warbler has a length between and centimeters is

Use a graphing utility to approximate the probability that a
randomly selected warbler has a length of 

(a) 13 centimeters or greater

(b) 15 centimeters or greater
