Let A ={2,3,6,8,9,11} and B ={1,4,5,10,15}. Let R be a relation on A × B defined by ( a, b ) R ( c, d ) if and only if 3 ad -7 bc is an even integer.…
Let $\displaystyle \mathrm{A}=\{2,3,6,8,9,11\}$ and $\displaystyle \mathrm{B}=\{1,4,5,10,15\}$. Let R be a relation on $\displaystyle \mathrm{A} \times \mathrm{B}$ defined by $\displaystyle (\mathrm{a}, \mathrm{b}) \mathrm{R}(\mathrm{c}, \mathrm{d})$ if and only if $\displaystyle 3 \mathrm{ad}-7 \mathrm{bc}$ is an even integer. Then the relation R is
