Find the Intersection of the Sets {5,6,7,8,9} union {1,2,3,4}
{5,6,7,8,9}{1,2,3,4}
Step 1
Set up the intersection notation of set {5,6,7,8,9} and {1,2,3,4}.
{5,6,7,8,9}{1,2,3,4}
Step 2
The intersection of two sets is the set of elements which are in both sets. The intersection in this case is an empty set.
