Conditional Probability
P(A|B) = P(A ∩ B) / P(B)P((A ∪ B)|F) = P(A|F) + P(B|F) - P((A ∩ B)|F)P(A'|B) = 1 - P(A|B)Multiplication Theorem
P(A ∩ B) = P(A) × P(B|A) = P(B) × P(A|B)P(A ∩ B ∩ C) = P(A) × P(B|A) × P(C|AB)P(A₁ ∩ A₂ ∩ ... ∩ Aₙ) = P(A₁) × P(A₂|A₁) × P(A₃|A₁A₂) × ... × P(Aₙ|A₁A₂...Aₙ₋₁)Independent Events
P(A ∩ B) = P(A) × P(B)P(A|B) = P(A) and P(B|A) = P(B)P(A₁ ∩ A₂ ∩ ... ∩ Aₙ) = P(A₁) × P(A₂) × ... × P(Aₙ)Bayes' Theorem
P(Eᵢ|A) = [P(Eᵢ) × P(A|Eᵢ)] / [∑ P(Eⱼ) × P(A|Eⱼ)]P(A) = ∑ P(Eᵢ) × P(A|Eᵢ)Get the complete formula sheet with derivations — continue in Super Tutor
