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.
| Student | Grade |
Arthur | 7
Jeff | 6
Anita | 7
Mitara | 8
Saree | 8
Bryan | 7
Micheal | 8
Susanna | 6
Maria | 6
To find the probability that an eighth grade student will NOT be selected, we first need to count the total number of students and then count the number of eighth grade students.
Total number of students = 9
Number of eighth grade students = 3
Therefore, the probability that an eighth grade student will NOT be selected is:
(9 - 3) / 9 = 6/9 = 2/3
As a percentage, this would be:
2/3 = 66.67%
