Question

Quizplus · Accepted Answer

A one-to-one correspondence between two sets requires that for every element in one set, there is a unique element in the other set, and vice versa. Since the empty set $\varnothing$ has no elements, it cannot be paired with any element of the set $\{ 69 \}$, making a one-to-one correspondence impossible.
