More Venn Diagrams (Grade 11 NSC Matric Mathematics): Flashcards

Visualise & count outcomes in event combinations

All possible outcomes

Outcomes belonging to all three events

$A \cap B \cap C$ - central region where all 3 events overlap

Outside all circles - no events occur

$A \cup B \cup C$ - union, anywhere inside any circle

$A \cap B$ - intersection where circles A and B overlap

$A \cup B$ - union, anywhere in circle A or B

$P = \frac{\text{favourable outcomes}}{\text{total outcomes}}$
