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.

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

Students: Arthur, Jeff, Anita, Miara, Saree, Bryan, Micheal, Susana, Marie.
Grade---:7, 6, 7, 8, 8, 7, 8, 6, 6.
The student names and grade levels are in order.

Answer 1

To find the probability that an eighth grade student will NOT be selected, we first need to determine how many eighth grade students there are in total. From the list, we see that there are three eighth grade students (Miara, Bryan, Susana) out of the total nine students.

The probability of NOT selecting an eighth grade student is then the number of non-eighth grade students divided by the total number of students, which is 6/9 or 2/3. This can also be represented as 66.67%.

Therefore, the probability that an eighth grade student will NOT be selected is 2/3 or 66.67%.
