The Law School Admission Test (LSAT) is a standardized exam issued four times a year for prospective law school candidates. The test is designed to assess a candidate in reading comprehension, as well as in their logical and verbal reasoning. The scores are adjusted to form a normal distribution with most scores falling in the 120 and 180 range, with a mean of 149 and a standard deviation of 8.5.

If a candidate who wrote the exam was selected at random, what is the probability that they achieved a score that was greater than 169 on the LSAT?
