Mathematics
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 points

Step-by-step explanation:
let the third side =x
x>26-19
or x>7
and x<26+19
x<45
so range is 7<x<45
