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.
To find the probability that an eighth grade student will NOT be selected, we need to first determine the total number of students in the bag and the number of eighth grade students in the bag.
Let's say there are 30 students in total and 10 of them are eighth graders.
Therefore, the probability of selecting an eighth grade student is 10/30 = 1/3.
The probability of NOT selecting an eighth grade student would then be 1 - 1/3 = 2/3.
Converting 2/3 into a percentage, we get 66.67%.
Therefore, the probability that an eighth grade student will NOT be selected is 66.67%.
