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. Grade 0 1 2 3 4 Number of Occurrences 3 6 4 3 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
