WebbIn the die-toss example, events A = f3g and B = f3;4;5;6g are not mutually exclusive, since the outcome f3g belongs to both of them. On the other hand, the events A = f3g and C = f1;2g are mutually exclusive. The union A[B of two events Aand B is an event that occurs if at least one of the events Aor B occur. The key word in the deﬁnition of the union is or. … WebbThe Total Probability Rule is a pivotal theorem in Probability and Statistics, and it is the foundation of other crucial theorems such as the Theorem of Bayes .

Tree-based models are a class of nonparametric algorithms that work by partitioning the feature space into a number of smaller (non-overlapping) regions with similar response values using a set of splitting rules.Predictions are obtained by fitting a simpler model (e.g., a constant like the average response value) in each region. slowest times for restaurants
