Probas :

p(A) = 1 - p(A barre)
p(A n B) = p(A) x p(B)
p(A) = p(A n B) + p(A n B barre)
p(A u B) = p(A) + p(B) - p(A n B)
p(A barre n B barre) = p(barre A u B)
p(barre A n B) = p(A barre u B barre)
P (petit R barre) (A) = p(A n R barre) / p(R barre) : partition de l'univers
P(B) = p(A1 n B) + p(A2 n B).....
2 evenements sont independants si P(A n B) = p(A) x p(B)
