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%.
Mrs. Baker’s students write word problems for homework. Each week she selects one student's word problem to display on a bulletin board. Each student's name is placed in a bag from which Mrs. Baker draws a name. What is the probability that an eighth grade student will NOT be selected? EXPLAIN your process and give your answer as a % or simplified fraction
