In order to calculate the probability that an eighth-grade student will NOT be selected, we need to first determine the total number of students and then the number of eighth-grade students.
Total number of students = 8
Number of eighth-grade students = 2 (Mitara and Saree)
Probability of not selecting an eighth-grade student = Number of non-eighth-grade students / Total number of students
Probability = 6 / 8
Probability = 3 / 4
Therefore, the probability is 3/4 or 75%.
Mrs. Baker's students write word problems each week, and she selects one student's word problem to display on a bulletin broad each week. Each student's name is placed in a bag from which Mrs. Baker draw a name. What is the probability that an eighth grade student will NOT be selected
