Answer:
In this diagram, "F" represents the set of students who study French, "G" represents the set of students who study German, "F∩G" represents the set of students who study both French and German, "G∩F" represents the same set but the order of the labels has been reversed to emphasize that this is the same set, and the numbers inside the diagram indicate how many students belong to each set.
Based on the given information, 13 students study French, 5 study only German (i.e., not French), and 6 study both French and German. Therefore, the number of students who study French only is 13 - 6 = 7.
Explanation:
To arrive at the number of students who study French only, we subtract the number of students who study both French and German (6) from the total number of students who study French (13), which gives us 7. This means that there are 7 students who study French but do not study German.
