Venn diagram

University students chose a foreign language for the 1st year. Of the 120 enrolled students, 75 chose English, 65 German, and 40 both English and German. Using the Venn diagram, determine:
- how many of the enrolled students chose English only
- how many of the enrolled students chose only German
- How many of the enrolled students chose English or German
- How many of the enrolled students chose neither English nor German

Correct result:

a =  35
n =  25
c =  100
d =  20


p=40 a=75p=7540=35
