Mutually Exclusive Events (HSC SSCE Mathematics Advanced): Flashcards

Events that cannot happen at same time in same experiment

$A cap B = emptyset$

Empty set (contains no elements)

Separate circles that do not overlap

$P(\overline{A}) = 1 - P(A)$

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

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

To avoid double-counting outcomes in both events

$0$ (zero)

$A \cap B \neq \emptyset$
