Explain how you are going to make a prediction based on the decision tree with an example. Here is an example of $2$ input variables $x1$ and $x2,$

and one predicted variable $Y$ : Leaf $1$ : $x1=1,Y=0$; Leaf $2$: $x1>1,x2=$ North, $Y=10$; Leaf $3$:$x1>1,x2=$ South or Middle, $Y=20+(2-x1{)}^{***}8.$
