**9. What are the most important formulas that I need to remember in Exercise 13.4?**

When E and F are events associated with the sample space S, and the probability of either one of them happening does not get affected by the happening of another, then these events E and Event F are independent. This implies E and F are independent when,

P(F | E) = P(F), where P (E) ≠ 0

P(E | F) = P(E), where P (F) ≠ 0

In case of three events A, B, C, they are mutually independent when,

P(A ∩ B) = P(A) P(B)

P(A ∩ C) = P(A) P(C)

P(B ∩ C) = P(B) P(C)

P(A ∩ B ∩ C) = P(A) P(B) P(C)
