Question

1. If a relation R on the set (1,2,3) be defined
by R = {(1,2), (3, 3)) then R is
(A) symmetric
(B) equivalence
(C) reflexive
(D) transitive​

Answer 1

Answer:

nothing anything it is neither reflexive nor symmetric and nor transitive so it is also not equivalance

Answer 2

(a,a )belong to relation R .then relation is reflexive.

If (a,b) (b,a) belong to relation R then realtion is symmetric.

If (a,b) (b,c) belong to R (a,c) also belong to relation R then relation is transitive.

If all above condition satisfy then relation is eqvivalance relation.
