Venn Diagram
A graphical representation of sample spaces and events using overlapping circles or regions, where the area (or size) of each region represents the probability of that combination of events.
Real World
Public health analysts at the UK Health Security Agency draw Venn diagrams to display overlapping groups of patients with flu and COVID symptoms simultaneously, making joint and individual probabilities immediately visible.
Exam Focus
Fill in the intersection region first, then work outward to individual-only regions — starting with outer regions is the most common Venn diagram mistake.
