Mrs. Benton selects one student's work to display on a bulletin board each week. Each student's name is placed in a bag from which Mrs. Benton draws a name. What is the probability that an eighth grade student will NOT be selected?
Responses
A 3/10
B 2/5
C 1/2
D 2/3
To find the probability that an eighth grade student will NOT be selected, we can find the total number of students and then subtract the number of eighth grade students.
Total number of students = 10
Number of eighth grade students = 4
Therefore, the probability that an eighth-grade student will NOT be selected = (10 -4)/10 = 6/10 = 3/5
So the correct answer is B. 3/5
