Reference: WJEC
Bounded regions represent intersections, written compactly as a single continuous interval using bounded inequalities.
Combining two inequalities joined by 'and' means intersecting their solution sets, and it is written with ∩.
Overlapping elements, meaning 'and', used to denote both events occurring, as in P(A ∩ B).
The event that both A and B occur, denoted A ∩ B.
