what do you mean by decision
tree what are the steps taken to build a decision tree ​

Answer 1

A decision tree starts from one end of the sheet of paper or the computer document, usually the left-hand side. The starting point extends in a series of branches or forks, each representing a decision, and it may continue to expand into sub branches, until it generates two or more results or nodes.

Definition: Decision tree analysis involves making a tree-shaped diagram to chart out a course of action or a statistical probability analysis. It is used to break down complex problems or branches. Each branch of the decision tree could be a possible outcome.
