If `R={(a,a),(a,c),(b,c),(b,b),(c,c),(a,b)}` on the set `X=(a,b,c)`, then how many subsets of R are reflexive relations?

Is R={(a,a),(b,b),(c,c),(a,c)} the identity relation on the set A={a,b,c} ?

R_(1)={(a,a),(a,b),(a,c),(b,b),(b,c),(c,a),(c,b),(c,c)} is defined on set A={a,b,c}. Find whether or not it is (i) reflexive (ii) symmetric (iii) transitive.

If A={a,b,c,d}. How many subsets does the set A have?

If A={a,b,c} and R={(a,a),(a,b),(b,c),(b,b),(c,c),(c,a)} is a binary relation of A, then which one of the following is correct?

If ={a,b,c} and R={(a,a),(a,b),(b,c),(b,b),(c,c),(c,a)} is a binary relation on A, then one of the following is correct?

Three relations R_(1),R_(2) and R_(3) are defined on a set A={a,b,c}: as for R_(1)={(a,a),(a,b),(a,c),(b,b),(b,c),(c,a),(c,b),(cc)} (a Find whether or not each of the relations R1, is Symmetric,reflexive or transitive.

Is the relation R = (a,a), (a,b), (b,b). Transitive on the set A = (a,b,c)?

Is the relation R={(a,b),(b,a)} on the set {a,b,c} reflexive ?

Let A={a,b,c} and R={(a,a),(b,b),(c,c),(b,c),(a,b)} be a relation on A, then R is :

Let R={(a ,\ a),\ (b ,\ b),\ (c ,\ c),\ (a ,\ b)} be a relation on set A={a ,\ b ,\ c} . Then, R is (a) identity relation (b) reflexive (c) symmetric (d) equivalence
