Question

Find the union of the following pair of sets.

$K=\{physicsteachers\}$ ; $L=\{Mathsteachers\}$

Answer 1

The union of set $K\&L$ is the set consisting of all elements which belong to either $K$ or $L$ or both. It is represented by $K\cup L$.

Given that $K=\left\{\text{physics teachers}\right\}$ and $L=\left\{\text{Maths teachers}\right\}$

$\therefore K\cup L=\left\{\text{Physics teachers or maths teachers}\right\}$
