Understanding a confusion matrix
One of the major tasks in machine learning and statistical testing is classification. In classification problems, we use a training set of labeled data to train our model to classify an unlabeled observation into one category or another. At the simplest level, this method uses observable data to make a related yes-or-no classification (like: will ...
How to use probability trees to evaluate conditional probability

While this isn’t a hard formula to plug values into, it doesn’t give an intuitive understanding ...
