Revision (Grade 12 NSC Matric Mathematics): Flashcards

Single result from an uncertain or random process

$S$ - complete collection of all possible outcomes

Collection of outcomes from an experiment

Between 0 and 1 (inclusive)

Outcomes in at least one of the events

Outcomes occurring in all events simultaneously

Events with no common outcomes, cannot happen together

Two mutually exclusive events covering all possible outcomes

First event's outcome has no influence on second event

$P(A \text{ or } B) = P(A) + P(B) - P(A \text{ and } B)$
