Both A and B<\/strong><\/p>\n<p>Naive Bayes is a probabilistic machine learning algorithm that is used for classification and regression tasks. It is based on Bayes&#8217; theorem, which is a mathematical formula that relates the probability of an event to the probability of other events that are known to be related to it.<\/p>\n<p>Naive Bayes assumes that all the features in a dataset are independent. This means that the value of one feature does not affect the value of any other feature. This assumption is often not true in real-world data, but it can still be a useful approximation.<\/p>\n<p>Naive Bayes also assumes that all the features in a dataset are equally important. This means that each feature contributes equally to the prediction of the target variable. This assumption is also often not true in real-world data, but it can still be a useful approximation.<\/p>\n<p>Despite these assumptions, Naive Bayes can be a very effective machine learning algorithm. It is relatively simple to understand and implement, and it can be used to solve a variety of problems.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li><strong>A.
