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.
Arthur = grade 7
Jett = grade 6
anita = grade 7
mitara = grade 8
saree = grade 8
bryan = grade 7
micheal = grade 8
susanna = grade 6
maria = grade 6
First, we need to count the total number of names in the bag: 9 names in total.
Out of the 9 students, 3 are eighth graders (Mitara, Saree, and Michael).
The probability of selecting an eighth grader is 3/9 or 1/3.
Therefore, the probability of NOT selecting an eighth grader is 1 - 1/3 = 2/3.
Expressed as a percentage, this is 66.67%.
