Answer 1

Here,

Given : Students from 125, 65 like to play football.....

75 like to play volleyball...

25 like to play both...

Now,

by using fromula,

n(A U B) = n(A) + n(B) - n(A U B)

= 65+75 - 25

= 140 - 25

= 115

Therefore, the students who don't like anything is 115...

Now we have to find... students who like only football...
