Question 1 of 30

In a scenario where a company is implementing an AI-driven voice recognition system to enhance customer service, they need to evaluate the effectiveness of the machine learning model used for speech recognition. The model\'s performance is assessed using precision and recall metrics. If the model correctly identifies 80 out of 100 positive instances (true positives) and incorrectly identifies 20 out of 100 negative instances (false positives), what is the precision of the model? Additionally, if there are 50 actual positive instances in total, what is the recall of the model?

Precision: 0.80, Recall: 0.60

Precision: 0.75, Recall: 0.80

Precision: 0.85, Recall: 0.50

Precision: 0.70, Recall: 0.70
