Answer 2

Answer:

We say that A and B have the same cardinality (written |A| = |B|) if a bijective correspondence exists between A and B. In other words, A and B have the same cardinality if it's possible to match each element of A to a different element of B in such a way that every element of both sets is matched exactly once.
