Inclusion–exclusion principle

For two non-disjoint sets $A$ and $B$, $|A| + |B|$ would involve counting $|A \cap B|$ twice. The following diagram shows how many times each region in Venn diagram is counted for $|A| + |B|$.

The question below is about three non-disjoint sets $A$, $B$ and $C$. Match the following diagrams to the correct expression. Like the diagram above, the ones below show how many times each region is counted.
