P b a c
SpletP(B A) = P(B) The last two are because if two events are independent, the occurrence of one doesn't change the probability of the occurrence of the other. This means that the probability of B occurring, whether A has happened or not, is simply the probability of B occurring. Continue with conditional probabilities. Table of Contents Splet16. dec. 2024 · P ( A, B) = P ( A B) P ( B) and this remains true when conditional on C: P ( A, B C) = P ( A B, C) P ( B C). You'll notice that the C conditioning seems to be "along for …

Pr ( B) = Pr ( ( A ∩ B) ∪ ( A ′ ∩ B)) by total probability law = Pr ( A ∩ B) + Pr ( A ′ ∩ B) because of mutual exclusion Pr ( A …
SpletOn en déduit que : p(A∩B) = p(B) × p(A/B) ; c'est la formule qui permet de calculer p(A?B) si l'on connait p(B) et p(A/B).
