Question

If the following pairs of sets are equivalent, enter $1$ or else enter $0$.

Set of whole numbers and set of multiples of $3$.

Answer 1

Two sets are equivalent if they have the same number of elements.
The set of whole numbers will have an infinite number of elements.

Also, the number of multiples of $3$ is infinite.

Thus, there is an infinite number of elements in the set of multiples of $3$.

Hence, the two sets are equivalent sets.
