Answer 2

Answer:

5

Step-by-step explanation:

Let A denote no of students who drink tea = 80

and B denote no of student who drink coffee= 60

20 drink both tea and cofee= A intersection B

Now ,

card(AUB) = card(A)+ card(B)- card( A intersection B)

=> card(AUB)= 80+60-20 = 120

AUB represent who drink tea or coffe

But we have find who Not drink tea or cofee

=> 125-120= 5

i.e. 5 Student who NOT drink tea or cofee.
