Show answer & explanation
Correct answer: C
Key idea: Sensitivity is also called recall or true positive rate.
TP: true positives, i.e. actual positives correctly predicted positive.
FN: false negatives, i.e. actual positives incorrectly predicted negative.
Sensitivity measures how many actual positives were correctly detected.
Formula: Sensitivity = TP / (TP + FN)
