symetrie(n n-p)=(np)
relation pascal:
  pr tt 1<k<n (n-1 k-1)+(n-1 k)=(nk)
   e(x)=nxp
   v(x)=nxpx(1-p)
   loi bernoulli ayant 2 issues 
   succes =1 p(X=1)=p
   echec =0 p(x=0)=1-p
n=nombre de fois quon fait lepreuve de bernou
p =proba davoir un succes pour une epreuve
ex 
on prend un pass paris 125 on veut savoir si ...
on definit le succes ... p(s)=
cette exp est une epreuve de B e parametre p=
on repete cette exp de maniere id et indep 125 fois
soit x la variable aleatoire qui compte ...
donc X suit la loi de bino de parametre ...
