Consider a node, t, in a decision tree. The set of training records in node t is Dt, which contains records from three different classes C1, C2, and C3. The class distribution is as follow:             Class                           Number of records               C1                                          x               C2                                          x               C3                                          2x What are the impurity measures of this node using Gini index and misclassification error?                              Gini index = Misclassification error =
