Front

What is the formula for the number of elements in the union of two sets?

Back

The formula is |A ∪ B| = |A| + |B| - |A ∩ B|.

Front

How many elements are in the set A = {1, 2, 3, 4, 5}?

Back

There are 5 elements in set A.

Front

What does it mean if two sets are disjoint?

Back

Two sets are disjoint if they have no elements in common, meaning A ∩ B = ∅.
