GPT 3.5 · Answer

First, we need to determine how many students are in the eighth grade. There are 3 eighth grade students: Mitara, Saree, and Michael. Out of a total of 9 students, the probability of selecting an eighth grade student is 3/9.

Therefore, the probability of NOT selecting an eighth grade student would be 1 - 3/9 = 6/9 or 2/3 or 66.67%.
