Exterior angle of a triangle is defined as the angle formed on one side of a triangle and when the adjacent side of the triangle is extended. Thus, there is only two angles form or legit to be called a pair of exterior angles. The said angles are located opposite of each and having the same value.

The probability would be 0.1971.

We will calculate a z-score for each end of this interval.

z = (X-μ)/σ

For the lower limit:
z = (1100-1050)/218 = 50/218 = 0.23

For the upper limit:
z = (1225-1050)/218 = 175/218 = 0.80

Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, the lower limit is 0.5910. The area under the curve to the left of, less than, the upper limit is 0.7881. To find the area between them, we subtract:

0.7881 - 0.5910 = 0.1971
