Mrs. Baker’s students write word problems each week, and she selects one student's word problem to display on a bulletin board each week. 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's in grade 7
Jeff is in grade 6
Anita is in grade 7
Mitara is in grade 8
Saree is in grade 8
Bryan is in grade 7
Micheal is in grade 8
Susanna is in grade 6
Maria is in grade 6
First, find out the total number of students in the bag: 9 students
Then, find the number of eighth grade students in the bag: 3 students (Mitara, Saree, and Michael)
To find the probability that an eighth grade student will NOT be selected, you need to find the number of students who are NOT in eighth grade (6 students) and divide it by the total number of students in the bag (9 students).
Therefore, the probability that an eighth grade student will NOT be selected is 6/9 or 2/3.
This can also be expressed as a percentage: (2/3) * 100 = 66.67%
