Question

State whether sets are disjoint:

X = {1, 3, 5, 7, 9}, Y = {0, 2, 4, 6, 8, 10}

Answer 1

Both the sets do not have even one element in common. Hence the sets X and Y are disjoint.

Answer 2

State whether sets are disjoint:

X = {1, 3, 5, 7, 9}, Y = {0, 2, 4, 6, 8, 10}

Answer :
             Disjoint sets are those sets in which none of the elements of one set matches with that of Other.
           Therefore , Disjoint sets have no common element .

Since there are no common elements in Set X and Set Y
  hence they are Disjoint sets!!

Hope this helps You!!

Thank You!!
