Answer 1

To find the probability that an eighth grade student will NOT be selected, we first need to determine how many eighth grade students there are out of the total number of students.

There are a total of 8 students. Out of the 8 students, there are 3 eighth grade students: Mitara, Saree, and Michael.

Therefore, the probability of NOT selecting an eighth grade student is 5 (total number of non-eighth grade students) out of 8 (total number of students), which can be simplified to 5/8.

To find this as a percentage, we can divide 5 by 8 and multiply by 100 to get 62.5%.

So, the probability that an eighth grade student will NOT be selected is 5/8 or 62.5%.
