What do you understand by precision and recall?
Recall is the number of relevant documents retrieved by a search divided by the total number of existing relevant documents, while precision is the number of relevant documents retrieved by a search divided by the total number of documents retrieved by that search.

What is recall formula?
Recall for Binary Classification In an imbalanced classification problem with two classes, recall is calculated as the number of true positives divided by the total number of true positives and false negatives. Recall = TruePositives / (TruePositives + FalseNegatives)
What is recall in machine learning?
Recall literally is how many of the true positives were recalled (found), i.e. how many of the correct hits were also found. Precision (your formula is incorrect) is how many of the returned hits were true positive i.e. how many of the found were correct hits.

Is high recall good?
Precision-Recall is a useful measure of success of prediction when the classes are very imbalanced. A high area under the curve represents both high recall and high precision, where high precision relates to a low false positive rate, and high recall relates to a low false negative rate.
