Revision (Grade 11 NSC Matric Mathematics): Flashcards

Likelihood of uncertain events occurring

Single result of a random process/experiment

All possible outcomes of experiment; symbol $S$

One or more outcomes from an experiment

Between 0 and 1 (0=never, 1=certain)

Times event occurs ÷ total trials

$A \cup B$: outcomes in at least one event

$A \cap B$: outcomes in all events simultaneously

Events with no common outcomes, can't occur together

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