In a math class students earned the following grades: 13 A's, 8 B's, 6 C's, 4 D's, and 1 F if the teacher pulled one exam from the pile at random, what are the chances that she would pull an exam that received a B?
8:32. Because it is 8 bs and then all of the grades added up. So, it would be 8:32. BUT! You have to simplify. So, 8:32, then, 2:8, and then, 1:6. So, answer is 1:6
