Between 0 and 1

$S$

$P(E) = \frac{n(E)}{n(S)}$

$f = \frac{p}{n}$ ($p$ = positive trials, $n$ = total trials)

Elements in at least one of the two sets (union)

Elements in both sets simultaneously (intersection)

All elements not in set $A$ (complement)

Events that cannot occur at the same time

$P(A) + P(A') = 1$

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$
