Intersection of Sets

The intersection of two sets is the listing of elements that are in both sets.

The Venn diagram below shows A ∩ B, where ∩ means ‘intersect’.

Example
If, U = {2, 4, 6, 8, 10, 12, 14, 16}
A = {4, 6, 8, 10, 12}
B = {2, 10, 12, 14}

Then, A intersect B, A ∩ B = {10, 12}

Note: A ∩ B’ = {4, 6, 8} and, A’ ∩ B = {2, 14}
