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.
There is a total of 9 students and 3 of those students are eighth graders
To calculate the probability that an eighth grade student will NOT be selected, we first need to determine the total number of students in the bag.
There are 9 students in total, with 3 of them being eighth graders. This means that there are 6 students who are not in eighth grade.
The probability of selecting an eighth grade student can be calculated by dividing the number of eighth graders by the total number of students:
3 eighth grade students / 9 total students = 1/3
To find the probability of NOT selecting an eighth grade student, we subtract the probability of selecting an eighth grade student from 1:
1 - 1/3 = 2/3
Therefore, the probability that an eighth grade student will NOT be selected is 2/3 or approximately 66.67%.
