# venn diagrams - How can this event be shown?

I have this venn diagram

For which i have shade (A ∩ B ) ∪ C. I see where A and B intersect, but i don't how a union should appear between the intersection and C. Could someone clarify where i am going wrong?

The red area is $(A\cap B)\cup C$
The red points are the ones that are either in the intersection $A\cap B$, or in $C$ (or in both, but there are no such points in this case). That's what union means, after all.
You simply shade $A \cap B$ which is the common area for $A$ and $B$, then you shade $C$ too because in a way you're "combining the two sets". All of what's in $A \cap B$ AND in $C$ is in the union.
