[AI-generated answer — Bot GPT 3.5]

There are a total of 9 students in the bag, and 3 of them are in 8th grade (Mitara, Saree, and Michael).

To calculate the probability that an 8th grade student will NOT be selected, we first find the probability of selecting an 8th grade student, which is 3/9 = 1/3.

Then, we find the probability of NOT selecting an 8th grade student by subtracting the probability of selecting an 8th grade student from 1: 1 - 1/3 = 2/3.

Therefore, the probability that an 8th grade student will NOT be selected is 2/3 or 66.67%.
