evenement =/ proba
PA(B)     =/ PB(A)

proba conditionnelle
PA(B)=P(AnB)/P(A)
<=>
PA(B)x P(A)= P(AnB)

feuille = ectremite dun chemin

regle 1
La somme des proba des branches
issues dun meme noeud est egale a 1
P(A)+P(B)= 1
 
regle 2
proba dune feuille est egale au
produit des proba du chemin
aboutissant a cette feuille

regle 3
(formule des proba totales)
la proba dun evenement associe
a plusieurs feuilles est egale
a la somme des proba de chacune
de ces feuilles
P(G)=P(RnG)+P(NnG)

independance
A et B independants si
P(AnB)= P(A)+P(B)
ou
PA(B)=P(B)
PB(A)= P(A)

Si A et B sont independants
alors A(barre) et B sont independants
