Write down A∪B for the following sets
The union of two sets  and  is the set of elements in or  (or both).
a.
if A={1,3,5} and B={2,4,6}, then A∪B={1,2,3,4,5,6}
b.
if A={1,3,5} and B={2,3,4}, then A∪B={1,2,3,4,5}
Write down A∩B for the following sets
The intersection of two sets and is the set of elements common to both and
a.
if A={1,3,5} and B={2,4,6}, then A∩B={} (there are no elements common to both and )
b.
if A={1,3,5} and B={2,3,4}, then A∩B={3}
