Yоu're building а decisiоn tree using the Gini impurity criteriоn. A pаrent node contаins 100 samples: 50 belong to class A, and 50 to class B. You are considering a binary split on a feature, resulting in the following two child nodes: Left Child: 40 samples — 40 of class A, 0 of class B Right Child: 60 samples — 10 of class A, 50 of class B What is the reduction in Gini impurity (Δ impurity) due to this split?
