Practice Flashcards: AP Statistics — probability and sampling distributions | Zestly

Question 1

Addition rule for non-mutually exclusive events

Accepted Answer

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

Question 2

Definition of independent events

Accepted Answer

Events A and B are independent if $P(A|B) = P(A)$.

Question 3

Accepted Answer

$Var(X + Y) = Var(X) + Var(Y)$
