Question

State whether the given set is finite or infinite.

$\mathrm{The}\mathrm{set}\mathrm{of}\mathrm{teachers}\mathrm{in}\mathrm{your}\mathrm{school}.$

Answer 1

Stating whether the given set is finite or infinite:

We know that,

A set that contains a countable number of different members or elements is called a finite set.

A set that contains unlimited number of different members or elements is called an infinite set.

Since the given set, $\mathrm{the}\mathrm{set}\mathrm{of}\mathrm{teachers}\mathrm{in}\mathrm{your}\mathrm{school}$ is countable,

Therefore, it is a finite set.
