The data tuples of Fig. 6.28 are sorted by decreasing probability value, as returned by a classifier. For each tuple, compute the values for the number of true positives $(T P)$ , false positives $(F P)$ , true negatives $(T N)$ , and false negatives $(F N)$ . Compute the true positive rate $(T P R)$ and false positive rate $(F P R)$ . Plot the ROC curve for the data.
