Question
The table gives the frequency distribution for the final grades in a course. (Here A=4, B=3,
C=2, D=1,F=0.) Determine the percentage of students who get a B or higher.

How could the answer be found?
OA. Add the number of occurrences for each grade that is a B or higher. Then, divide
by the number of grades.
OB. Find the probability of each grade. Then, add them together to find the percent
OC. Find the probability of each grade that is a B or higher. Then, find the average of
those probabilities.
OD. Find the probability of each grade. Then, add the probabilities for the grades that
are a B or higher together to find the percent.
The percentage of students who get a B or higher is
