To determine the probability that an eighth-grade student will NOT be selected, we first need to count how many eighth-grade students there are in the class. From the list provided, we see that there are three eighth-grade students: Mitara, Saree, and Micheal.
Next, we need to count the total number of students in the class. From the list provided, we see that there are nine students in total.
Therefore, the probability that an eighth-grade student will NOT be selected is calculated by taking the number of non-eighth-grade students (6) divided by the total number of students (9):
6 (non-eighth-grade students) / 9 (total students) = 2/3
Hence, the probability that an eighth-grade student will NOT be selected is 2/3, which is equivalent to 66.67%.
