True Positive (TP): When the model correctly predicts a positive outcome — i.e., the actual value is positive and the model also predicts it as positive.
This is a 1-mark definition question from the Confusion Matrix topic (Chapter 3). Examiners expect the key idea: correct prediction of a positive class. Mention both conditions — actual is positive AND predicted is positive. Avoid confusing it with False Positive (actual negative, predicted positive).
