    \begin{exercice}
On a représenté graphiquement ci-dessous une variable aléatoire suivant une loi binomiale.\smallskip


    \begin{tikzpicture}[general,xscale=0.3,yscale=15]

 \draw[quadrillageNIV2, xstep=2, ystep=0.02] (-2,-0.02) grid (22,0.22);

\axeX{-2}{22}{2,4,6,8,10,12,14,16,18,20};
\axeY{-0.02}{0.21}{0.02,0.10,0.2};

\clip(-2,-0.02) rectangle (22,0.21);


\draw[fill, fill opacity=1,color=A1] (1.9,0) rectangle (2.1,0.01);
\draw[fill, fill opacity=1,color=A1] (2.9,0) rectangle (3.1,0.03);
\draw[fill, fill opacity=1,color=A1] (3.9,0) rectangle (4.1,0.06);
\draw[fill, fill opacity=1,color=A1] (4.9,0) rectangle (5.1,0.12);
\draw[fill, fill opacity=1,color=A1] (5.9,0) rectangle (6.1,0.16);
\draw[fill, fill opacity=1,color=A1] (6.9,0) rectangle (7.1,0.18);
\draw[fill, fill opacity=1,color=A1] (7.9,0) rectangle (8.1,0.17);
\draw[fill, fill opacity=1,color=A1] (8.9,0) rectangle (9.1,0.13);
\draw[fill, fill opacity=1,color=A1] (9.9,0) rectangle (10.1,0.08);
\draw[fill, fill opacity=1,color=A1] (10.9,0) rectangle (11.1,0.04);
\draw[fill, fill opacity=1,color=A1] (11.9,0) rectangle (12.1,0.02);
\draw[fill, fill opacity=1,color=A1] (12.9,0) rectangle (13.1,0.01);

\end{tikzpicture}
Donner une valeur approchée de $P(X=3)$ puis de $P(X\geqslant 10)$.

\begin{corrige}
Graphiquement :
\begin{itemize}
  \item $P(X=3)\approx \nombre{0,03}$
  \item $P(\geqslant 10)\approx \nombre{0,15}$
\end{itemize}
    \end{corrige}
