Let A = { 1,2,3 } , then number of relations containing {1,2} and {1,3} , which are reflexive and symmetric but not transitive is :

Let A = {1, 2, 3} Then number of relations containing (1, 2) a n d (1, 3) which are reflexive and symmetric but not transitive is (A) 1 (B) 2 (C) 3 (D) 4

Let A={1,\ 2,\ 3} . Then, show that the number of relations containing (1, 2) and (2, 3) which are reflexive and transitive but not symmetric is three.

Give an example of a relation which is reflexive and symmetric but not transitive.

If A={1,3,5} , then the number of equivalence relations on A containing (1,3) is

Let A = {1, 2, 3} . Then number of equivalence relations containing (1, 2) is (A) 1 (B) 2 (C) 3 (D) 4

Let A = {1, 2, 3} . Then number of equivalence relations containing (1, 2) is (A) 1 (B) 2 (C) 3 (D) 4

If A = {1,2,3} and R = { (1,1}, ( 2,2), (3,3)} then R is reflexive, symmetric or transitive?

If A={1,\ 2,\ 3,\ 4} define relations on A which have properties of being symmetric but neither reflexive nor transitive.

Give an example of a relation which is transitive but neither reflexive nor symmetric.

The relation R in the set {1,2,3} given by R = {(1,2), (2,1),(1,1)} is a) symmetric and transitive, but not reflexive b) reflexive and symmetric, but not transitive c) symmetric, but neither reflexive nor transitive d) an equivalence relation
