  1. What is the addition rule for probability?
    P(A or B) = P(A) + P(B) - P(A and B)
  2. What is the formula for conditional probability?
    P(A|B) = P(A. and B)/P(B)
  3. What is the multiplication rule for probability?
    P(A and B) = P(A|B) x P(B)
  4. How can you calculate if A and B are independent?
    • P(A|B) = P(A)
    • P(A and B) = P(A) x P(B)
  5. How do you know if A and B are mutually exclusive?
    P(A and B) = 0
