Question

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? There are nine kids and three of them are eighth-graders

EXPLAIN your process and give your answer as a % or simplified fraction.

Answer 1

There are a total of nine students, and three of them are eighth-graders. Therefore, there are six students who are not eighth-graders.

The probability of an eighth-grade student not being selected can be calculated by taking the number of non-eighth-grade students (6) divided by the total number of students (9), which equals 6/9 or 2/3.

Converting 2/3 to a percentage, we get 66.67%. Therefore, the probability that an eighth-grade student will NOT be selected is 66.67%.
