Basic Concepts and Sample Space
P(E) = Number of favorable outcomes / Total number of outcomesP(E) = n(E) / n(S)Types of Events
Algebra of Events
P(A') = 1 - P(A)P(A ∪ B) = P(A) + P(B) - P(A ∩ B)P(A ∪ B) = P(A) + P(B)P(A - B) = P(A ∩ B') = P(A) - P(A ∩ B)Addition Theorems
P(A ∪ B ∪ C) = P(A) + P(B) + P(C) - P(A ∩ B) - P(B ∩ C) - P(A ∩ C) + P(A ∩ B ∩ C)P(A ∪ B ∪ C) = P(A) + P(B) + P(C)P(exactly one of A,B,C) = P(A) + P(B) + P(C) - 2P(A∩B) - 2P(B∩C) - 2P(A∩C) + 3P(A∩B∩C)P(exactly two of A,B,C) = P(A∩B) + P(B∩C) + P(A∩C) - 3P(A∩B∩C)P(at least two of A,B,C) = P(A∩B) + P(B∩C) + P(A∩C) - 2P(A∩B∩C)Get the complete formula sheet with derivations — continue in Super Tutor
