Answer 1

To find the probability that an eighth grade student will NOT be selected, we first need to determine the total number of students in the bag and the number of eighth grade students in the bag.

Let's say there are 25 students in the bag, with 10 of them being eighth graders.

The probability of not selecting an eighth grade student can be calculated by taking the number of non-eighth grade students (total students - eighth grade students) and dividing it by the total number of students.

So, the probability of not selecting an eighth grade student is:

(25 - 10) / 25 = 15/25 = 3/5 = 60%

Therefore, the probability that an eighth grade student will NOT be selected is 60%.
