How to draw this tree diagram?

Question

How can I draw this tree diagram in LaTex?

Answer 1

Welcome to TeX-SE! This is to give you a start. I am convinced that you could also add the H and T programmatically, but I do not have motivation now to spell this out (the more so since I am not sure if that's what you want).

\documentclass{article} 
\usepackage[edges]{forest}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{forest}
for tree={s sep=0cm,l sep=1.2cm,font=\sffamily,
where n children=0{rotate=90,anchor=west,edge={thick,-{Latex}}}{},
edge={thick}
}
  [H,alias=L1
   [H,alias=L2
    [H,alias=L3
     [H,alias=L4
      [H,alias=L5
       [HHHHH,alias=L6]
      ]
      [T
       [HHHHT]
      ]
     ]
     [T
      [H
       [HHHTH]
      ]

    ]
   ]
  ]
\foreach \X [count=\Y] in {First,Second,Third,Fourth,Fifth} 
{\node[anchor=east,font=\sffamily] at (L6.north|-L\Y){\X\ flip};} 
\node[anchor=east,font=\sffamily] at (L6.north){Outcome}; 
\end{forest}
\end{document}

*NOTE**: Almost everything I know about forest I learned from some answers by cfr, who really is a forest master. If you consider upvoting this, please upvote some answer(s) by her instead. That way you will certainly cast a deserved upvote.
