Summary (Grade 11 NSC Matric Mathematics): Flashcards

A single result from an experiment

All possible outcomes of an experiment

Collection of one or more outcomes

Between 0 and 1 (inclusive)

Events that cannot happen at the same time

Two mutually exclusive events covering all outcomes

Events where one doesn't affect the other's probability

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

$P(\text{not } A) = 1 - P(A)$

$P(A \text{ and } B) = P(A) \times P(B)$
