Formula Sheet — Probability

Important formulas and equations from Probability for AP EAPCET Mathematics.

Formulas — Probability

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)
