Let $R = \{(a, a)\}$ be a relation on a set $A$. Then $R$ is
Symmetric
Antisymmetric
Symmetric and antisymmetric
Neither symmetric nor anti-symmetric
(c) It is obvious.
Determine whether each of the following relations are reflexive, symmetric and transitive:
Relation $R$ in the set $A$ of human beings in a town at a particular time given by
$R =\{(x, y): x$ and $y$ live in the same locality $\}$
Let $R$ and $S$ be two equivalence relations on a set $A$. Then
The relation $R= \{(1, 1), (2, 2), (3, 3), (1, 2), (2, 3), (1, 3)\}$ on set $A = \{1, 2, 3\}$ is
$R$ is a relation over the set of real numbers and it is given by $nm \ge 0$. Then $R$ is
The void relation on a set $A$ is
