The automation of the inspections performed by a quality controller is considered. By providing as training data 10,000 product images and the results of judgments by the quality controller about whether each product is defective or not, a machine learning model is created to judge whether a product is defective or not. The results of a test judgement by a machine learning model on 100 product images are as shown in the table. When the ratio of the number of images that product is judged to be defective by the machine learning model out of the images that product is judged to be defective by the quality controller is deemed to be the recall rate, what is the recall rate in this test judgement?
