Formula Review
A and B are events
P(S) = 1 where S is the sample space
0 ≤ P(A) ≤ 1
P(A|B) =
If A and B are independent, P(A AND B) = P(A)P(B), P(A|B) = P(A), and P(B|A) = P(B).
If A and B are mutually exclusive, P(A OR B) = P(A) + P(B) and P(A AND B) = 0.
The multiplication rule—P(A AND B) = P(A|B)P(B)
The addition rule—P(A OR B) = P(A) + P(B) − P(A AND B)
