1.	What is Precision? Mention its formula.
Answer» Precision is defined as the percentage of true positive cases versus all the cases where the prediction is true. Precision = \(\cfrac{True\,Positives}{All\,Predicted\, Positives}\) x 100% That is, it takes into account the True Positives and False Positives. Precision = \(\cfrac{TP}{TP + FP}\) x 100%

Answer»

Precision is defined as the percentage of true positive cases versus all the cases where the prediction is true.

Precision = \(\cfrac{True\,Positives}{All\,Predicted\, Positives}\) x 100%

That is, it takes into account the True Positives and False Positives.

Precision = \(\cfrac{TP}{TP + FP}\) x 100%
