Set Notation & Conditional Probability (AQA A-Level Mathematics): Flashcards

$\mathcal{E}$

$\emptyset = \{\}$

Elements common to both sets $A$ and $B$

Elements in either set $A$ or set $B$, or both

All elements not in $A$

Events that cannot occur at the same time

$P(A \cap B) = 0$

Outcome of one does not affect probability of the other

$P(A \cap B) = P(A)P(B)$

$n(A)$ or $|A|$
