What is the addition rule for probabilities?

Back

The addition rule states that P(A or B) = P(A) + P(B) - P(A and B) for any two events A and B.

What is the multiplication rule for independent events?

Back

For independent events A and B, the multiplication rule states that P(A and B) = P(A) * P(B).
