E(X)=p V(X)=p(1-p)

Formule de Bernoulli: 
  P(X=k)=n|k p^k(1-p)^n-k

Espérence et variance d'une loi binomiale:
 
  E(X)=n×p
  V(X)=n×p×(1-p)


On considere l'epreuve de Bernoulli qui a pour succes:
On repete x fois l'experience de facon identique et independante.
On a donc un schéma de Bernoulli de parametre n= et p=
--------------------------------
FORMULE: 
  P(A inter B)=P(A) x P(B)
  P B(A)=P(A inter B)/P(B)

------------------------------
PROBA TOT:
  P(A)=P(A inter B)+P(A inter B')+...
