What is the addition rule of probability?

• The addition rule of probability states that P(A or B) = P(A) + P(B)

• The addition rule of probability states that P(A or B) = P(A) - P(B)

• The addition rule of probability states that P(A or B) = P(A) * P(B)

• The addition rule of probability states that P(A or B) = P(A) + P(B) - P(A and B)
