The union of set A and set B, A∪B , is the set consists of
all the elements in set A and set B.
the common elements in set A and set B.
all the elements in set A but not in set B.
all the elements in set B but not in set A.
The Venn diagram for A∪B is represented in green as
The elements in P∪Q are
{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
{0, 1, 2, 3, 8, 9, 10}
{4, 5, 6, 7}
{ }
Base on the Venn diagram given, the n(P∪Q) is
