If `A={1,2,3},` the number of symmetric relations in `A` is

If A={1,2,3} the number of symmetric realtions in A is

If A={1,2,3,4} then find number of symmetric relation on A which is not reflexive is

Consider set A = { 1,2,3}. Number of symmetric relations that can be defined on A containing the ordered pair (1,2) & (2,1) is

Consider set A={1,2,3}. Number of symmetric relations that can be defined on A containing the ordered pair (1,2)&(2,1) is

If n(A) = 4, then number of symmetric relations that can be defined on A is

Let A = {1, 2, 3}, then number of relations containing (1, 2) and (1, 3) which are reflexive and symmetric but not transitive is (a) 1, (b) 2, (c) 3, (d) 4 .

If the numbers of different reflexive relations on a set A is equal to the number of different symmetric relations on set A, then the number of elements in A is

If the numbers of different reflexive relations on a set A is equal to the number of different symmetric relations on set A, then the number of elements in A is

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