Answer:

a) 26 students

b) 17 students

c) 74 students

Step-by-step explanation:

We can make a Venn diagram and make sense a lot of things

a) The number of students who takes French but not German = the number of students who takes French - the number of students who takes French and German = 65 - 20 = 45 students

The number of students who takes French Only = The number of students who takes French but not German - the number of students who take French and Spanish + the number of students who take all 3 languages = 45 - 22 + 3 = 26 students.

b) The number of students who take French AND German but not Spanish = the number of students who takes French and German - the number of students who take all 3 languages = 20 - 3 = 17 students

c) The number of students who take French OR German but not Spanish = the number of students who take French Only + the number of students who take German - the number of students who take German and Spanish = 26 + 60 - 12 = 74 students.
