The more trials we observe of any random process, the proportion of times that a specific outcome occurs approaches its probability
Complement Rule
P(A) = 1 - P(Ac)
Mutually Exclusive Events
P(A∩B) = 0
Addition Rule for Mutually Exclusive Events
P(AUB) = P(A) + P(B)
General Addition Rule
P(AUB) = P(A) + P(B) - P(A∩B)
Conditional Rule
P(A|B) = P(A∩B)/P(B)
Independent Events
P(A|B) = P(A|Bc) = P(A)
Never
Mutually exclusive events can ? be independent
General Multiplication Rule
P(A∩B) = P(A) x P(B|A)
Multiplication Rule for Independent Events
P(A∩B) = P(A) x P(B)
