Question

State whether sets are disjoint:

R = { a , b , c , d , e }, S = { d , e , a , b , c }

Answer 1

Both the sets have the same elements and hence they are equal sets . They have common elements and hence they are NOT disjoint

Answer 2

R={a,b,c,d,e}
S={d,e,a,b,c}
They are not disjoint as they contain all the same elements in them.
