∩
Intersection
The set intersection operator: A ∩ B is the set of elements common to both A and B. The cap opens downward, mirroring ∪; the pair should always come from the same font so their bowls match. Central to probability notation (P(A ∩ B)) and Venn-diagram captions. Space it on both sides as a binary operator.
