Mrs. Baker's student 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 need to first count the total number of students in the bag and then count the number of eighth grade students.
There are 9 students in total:
- 3 eighth grade students
- 6 non-eighth grade students
The probability of selecting an eighth grader is 3/9 = 1/3.
Therefore, the probability of NOT selecting an eighth grader is 1 - 1/3 = 2/3 = 66.67%.
So, the probability that an eighth grade student will NOT be selected is 66.67%.
