To determine how many adults age 25 and older did not earn a college degree, we would need the specific frequency table mentioned in your question. Since I can't see that table, I can't provide an exact answer.
Typically, the number of adults who did not earn a college degree can be found by summing the number of adults who have completed only high school and those who have not completed high school.
If you can provide the relevant numbers from the frequency table, I can help you calculate the total or choose the best answer from the options A, B, C, or D.
