Question

Quizplus · Accepted Answer

To find the number of students taking Statistics but not Finite Mathematics, we need to subtract the number of students taking both from the total number taking Statistics. 
476 total taking Statistics - 85 taking both = 391 taking Statistics only. Therefore, the answer is B. To find the number of students taking Statistics but not Finite Mathematics, we need to subtract the number of students taking both Finite Mathematics and Statistics from the total number of students taking statistics.

Number of students taking Statistics = 476 
Number of students taking both Finite Mathematics and Statistics = 85

Therefore, the number of students taking Statistics but not Finite Mathematics = 476 - 85 = 391.

Hence, the best choice is B.
