Quizplus · Accepted Answer

To find the number of students who take biology but not history, we need to subtract the students who take both subjects from the total number of students who take biology. Therefore, 17 (total number of biology students) minus 8 (students who take both) is equal to 9. Therefore, the correct answer is D) 9. To find the number of students who take biology but not history, we need to subtract the number of students taking both history and biology from the total number of students taking biology. 
Total number of students taking biology = 17 
Number of students taking both history and biology = 8 
Number of students taking biology but not history = 17 - 8 = 9 
Therefore, the correct answer is D) 9.
