You have scored your Nave Bayesian Classifier model on hold out test data for cross
validation. You have determined the way the samples scored and have tabulated them as
shown in the exhibit.

What are the Precision and Recall rates of the model?

Option A

Precision = 262/277 Recall = 262/288

Option B

Precision = 262/277 Recall = 262/288

Option C

Precision = 277/262 Recall = 288/262

Option D

Precision = 288/262 Recall = 277/262

Correct Answer A
Explanation
