Elementary Probability Rules Given two events A and B, basic probability rules can help us determine the probability of the union or intersection of the events.

The 'AND' rule: the multiplication rule If A and B are independent events P (A and B) = P (A) × P (B) Example Rory rolls a dice and tosses a coin at the same time.

In this note we wish to pass along an example that we have found useful when introducing the concepts of conditional probability and Bayes' Rule to undergraduate students. The advantages of this ...
