次の確率ツリーを LaTeX で作成するにはどうすればよいですか?
助けてくれてありがとう！！

答え1
最も複雑なツリーはここにあります。これを変更して、より単純なツリーを作成することができます。行き詰まった場合は、コードを投稿して、遭遇した問題の解決方法を尋ねてください。
forestこれは、ツリーの描画に標準の括弧表記を使用できる強力なパッケージを使用します。以前の質問に対する私の答えforestツリーをブラケット仕様に変換する方法を紹介し、説明します。

括弧表記を理解するには、上にリンクした回答を参照してください。そうしないと、これは単なる魔法のトリックのように見え、適応することは不可能になります ;)。
