Answer 2

you can use Venn diagram to solve this question and its should be two cases like ¹if A,B,C intersect at one point then relation BTW A ,Band C is A u B u C =A+B+C-(A intersection C)-(B inter C)-(C inter A) +(A inter B inter C),if third part of this eq becomes zero then there is no relation BTW a,b,c if not then relation exists.
