![**Question 14**
In her MAT135 class, Professor Alayeb found that the mean score of the first exam was 48. Suppose that the scores are normally distributed with a standard deviation of 11 points.
1. What is the probability that a randomly selected score is less than 59? (use 2 decimals)
\( P(x<59) = \) [ ]
2. What is the probability that a randomly selected score is more than 81? (use 2 decimals)
\( P(x>81) = \) [ ]
