Define a relation $R$ over a class of $n \times n$ real matrices $A$ and $B$ as $"ARB$ iff there exists a non-singular matrix $P$ such that $PAP ^{-1}= B "$ Then which of the following is true?
$R$ is symmetric, transitive but not reflexive.
$R$ is reflexive, symmetric but not transitive
$R$ is an equivalence relation
$R$ is reflexive, transitive but not symmetric
Show that the relation $R$ in the set $\{1,2,3\}$ given by $R =\{(1,2),(2,1)\}$ is symmetric but neither reflexive nor transitive.
The void relation on a set $A$ is
The probability that a relation $R$ from $\{ x , y \}$ to $\{ x , y \}$ is both symmetric and transitive, is equal to
Let $R$ be a relation on $N$ defined by $x + 2y = 8$. The domain of $R$ is
The number of symmetric relations defined on the set $\{1,2,3,4\}$ which are not reflexive is
