A model is used to predict whether an email is spam or not spam. Out of 200 emails: 90 emails are spam, and 110 are not spam. The model predicted 85 spam emails correctly and 5 spam emails as not spam. It predicted 100 emails as not spam correctly and 10 non-spam emails as spam.
True Positives (TP) = 85, False Negatives (FN) = 5
True Positives (TP) = 85, False Negatives (FN) = 10
c) True Negatives (TN) = 85, False Positives (FP) = 5
