This is only about how to draw the counting tree, using the istgame package:

enter image description here

\documentclass{article}

\usepackage{istgame}


\begin{document}


%% tree
\begin{istgame}[scale=.7,font=\scriptsize]
\tikzset{oval node/.style={ellipse node,draw=none}}
\setistgrowdirection'{east}
\xtdistance{14mm}{60mm}
\istrooto(A){start}   \istb \istb \istb \endist
\xtdistance{12mm}{20mm}
\istrooto(0)(A-1){0}  \istb \istb \istb \endist
\istrooto(1)(A-2){1}  \istb \istb \istb \endist
\istrooto(2)(A-3){2}  \istb \istb \istb \endist
\xtdistance{10mm}{10mm}
\istrooto(00)(0-1){0}
  \istb{}{0 \quad 2^03^07^0=1}
  \istb{}{1 \quad 2^03^07^1=7}
  \endist
\istrooto(01)(0-2){1}
  \istb{}{0}
  \istb{}{1}
  \endist
\istrooto(02)(0-3){2}
  \istb{}{0}
  \istb{}{1}
  \endist
\istrooto(10)(1-1){0}
  \istb{}{0}
  \istb{}{1}
  \endist
\istrooto(11)(1-2){1}
  \istb{}{0}
  \istb{}{1}
  \endist
\istrooto(12)(1-3){2}
  \istb{}{0}
  \istb{}{1}
  \endist
\istrooto(20)(2-1){0}
  \istb{}{0}
  \istb{}{1}
  \endist
\istrooto(21)(2-2){1}
  \istb{}{0}
  \istb{}{1}
  \endist
\istrooto(22)(2-3){2}
  \istb{}{0 \quad 2^23^27^0=36}
  \istb{}{1 \quad 2^23^27^1=252}
  \endist


\node [anchor=mid] at ([yshift=-1.3cm,xshift=-1.2cm]22) {a};
\node [anchor=mid] at ([yshift=-1.3cm]22) {b};
\node [anchor=mid] at ([yshift=-1.3cm,xshift=1.3cm]22) {c};
\end{istgame}

  • Thank for your help. I already did this, the only thing that I don't is how to make the letters a b c at the bottom. Now you solve it completely, and I also learn about istgame (this is new for me) package in your solution, thank you very much. I hope I can solve at least one of another users qeustion. – erdos Sep 30 '20 at 23:25

with forest

\documentclass[margin=3mm]{standalone}
\usepackage{forest}
\usetikzlibrary{positioning}

\begin{document}
    \begin{forest}
for tree = {font=\scriptsize,
            anchor=west,
            math content,
            grow'=0,
            s sep=2mm,
            l sep=7mm
            }
[start
    [0
        [0  [0\quad {2^{0} 3^{0} 7^{0}=1}]
            [1\quad {2^03^07^1=7}]
        ]
        [1  [0] [1]
        ]
        [2  [0] [1]
        ]
    ]
    [1
        [0  [0] [1]
        ]
        [1  [0] [1]
        ]
        [2  [0] [1]
        ]
    ]
    [2, name=aux1
        [0  [0] [1]
        ]
        [1  [0] [1]
        ]
        [2, name=aux2

            [0\quad {2^{2}3^{2}7^{0}=36}] 
            [1\quad {2^{2}3^{0}7^{1}=252}, name=aux3]
        ]
    ]
]
\node (a) [below,xshift=5pt]   at (aux3.south west)   {c};
\node               at (aux2 |- a)   {b};
\node               at (aux1 |- a)   {a};
   \end{forest}
\end{document}

For placement in your document you need first to show an example (with dummy text) of your document. It should be simple with inserting figures with above image on the right place in it.
