There are a total of 9 students in the class.
To find the probability that an eighth grade student will not be selected, we need to first find the total number of eighth grade students in the class. There are 3 eighth grade students (Mitara, Saree, and Michael).
So, 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
Therefore, the probability that an eighth grade student will not be selected is 2/3 or approximately 66.67%.
