The probability is 0.1587.
The z-score associated with this is found using the formula
z = (X-μ)/σ = (100-90)/10 = 10/10 = 1.0
Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this is 0.8413. We want the area greater than, so we subtract from 1:
1 - 0.8413 = 0.1587
