Webb5 jan. 2024 · If we let event A be the event of choosing a Spade and event B be the event of choosing a Queen, then we have the following probabilities: P (A) = 13/52 P (B) = 4/52 P (A∩B) = 1/52 Thus, the probability of choosing either a Spade or a Queen is calculated as: P (A∪B) = P (A) + P (B) – P (A∩B) = (13/52) + (4/52) – (1/52) = 16/52 = 4/13. Formally, P(A B) is defined as the probability of A according to a new probability function on the sample space, such that outcomes not in B have probability 0 and that it is consistent with all original probability measures. Let Ω be a discrete sample space with elementary events {ω}, and let P be the probability measure with respect to the σ-algebra of Ω. Suppose we are told that the event B ⊆ Ω has occurred.
