What is the formula for precision?

Consider a model that predicts 150 examples for the positive class, 95 are correct (true positives), meaning five were missed (false negatives) and 55 are incorrect (false positives).

Is F1 Score same as accuracy?

Accuracy is used when the True Positives and True negatives are more important while F1-score is used when the False Negatives and False Positives are crucial.In most real-life classification problems, imbalanced class distribution exists and thus F1-score is a better metric to evaluate our model on.
