Some nations require their students to pass an exam before earning their primary school degrees or diplomas. A certain nation gives students an exam whose scores are normally distributed with a mean of 41 4141 points and a standard deviation of 9 99 points. Suppose we select 2 22 of these testers at random, and define the random variable d dd as the difference between their scores. We can assume that their scores are independent. Find the probability that their scores are within 10 1010 points of each other. You may round your answer to two decimal places.
