3. - 5. You have grown a classification tree to predict a patient's physician rating. Suppose the distribution of ratings at one terminal node is:

Excellent 0.4

Good 0.2

Fair 0.3

Poor 0.1

Calculate the misclassification rate, the Gini index, and the entropy value for this terminal node. Here are the definitions of these 3 measures, as shown in the slides. As we're considering only a single terminal node, you can ignore the subscript m, which just refers to the mth node.
