Wie erstelle ich die folgenden Wahrscheinlichkeitsbäume in LaTeX?

Danke für die Hilfe!!

Antwort1

Hier ist der komplexeste Baum. Sie sollten ihn ändern können, um einfachere Bäume zu erstellen. Wenn Sie nicht weiterkommen, posten Sie einfach den Code, den Sie haben, und fragen Sie, wie Sie das aufgetretene Problem lösen können.

Dabei wird das leistungsstarke forestPaket verwendet, das die Verwendung der Standardklammernotation zum Zeichnen von Bäumen ermöglicht.Meine Antwort auf eine frühere Fragestellt vor forestund erklärt, wie man einen Baum in eine Klammerspezifikation umwandelt.

Schauen Sie sich die Antwort an, die ich oben verlinkt habe, um Hilfe beim Verständnis der Klammernotation zu erhalten. Sonst wird Ihnen das wie ein Zaubertrick vorkommen und Sie werden es nicht umsetzen können ;).
