The probability is 0.2177.
The z-score associated with this income is
z = (525-490)/45 = 0.78
Using a z-table (http://www.z-table.com) we see that the area to the left of this score, less than the score, is 0.7823. We want the probability greater than this score, so we subtract from 1:
1 - 0.7823 = 0.2177.
