To find the probability that an eighth grade student will NOT be selected, we need to first determine the total number of students in the class and then find the number of eighth grade students.
Let's assume there are a total of 30 students in Mrs. Baker's class. Out of these 30 students, there are 15 eighth grade students.
The probability of selecting an eighth grade student is:
Number of eighth grade students / Total number of students = 15/30 = 1/2
Therefore, the probability of NOT selecting an eighth grade student is:
1 - 1/2 = 1/2
So, the probability that an eighth grade student will NOT be selected is 1/2 or 50%.
