Answer 2

Answer:

An empty relation (or void relation) is one in which there is no relation between any elements of a set. For example, if set A = {1, 2, 3} then, one of the void relations can be R = {x, y} where, |x – y| = 8.

Universal relation is a relation on set A when A X A ⊆ A X A. In other words, universal-relation is the relation if each element of set A is related to every element of A. For example : Relation on the set A = {1,2,3,4,5,6} by. R = {(a,b) ∈ R : |a -b|≥ 0}
