### Understanding Frequency Distribution for Grades

The table below provides the frequency distribution for final grades in a course. The grades are represented as follows: A = 4, B = 3, C = 2, D = 1, F = 0. The task is to determine the percentage of students who received a grade of D or higher.

| Grade | Number of Occurrences |
|-------|-----------------------|
| 0     | 5                     |
| 1     | 2                     |
| 2     | 8                     |
| 3     | 4                     |
| 4     | 6                     |

### How to Calculate the Percentage

The process to find the percentage of students who obtained a D or higher is outlined through different options:

- **Option A:** Calculate the probability of each grade, then add them together to find the percentage.
  
- **Option B:** Calculate the probability of each grade that is D or higher, then find the average of those probabilities.
  
- **Option C:** Add the number of occurrences for each grade that is D or higher, then divide by the total number of grades.
  
- **Option D (Correct Answer):** Calculate the probability of each grade. Then, add the probabilities for the grades that are D or higher to find the percentage.

The formula to use is:

\[ \text{Percentage of students who get a D or higher} = \% \]

Here, Option D is highlighted as the correct methodology.
