What you’ll learn to do: calculate and understand different probabilities for a given contingency table

Tables were used in previous modules to organize data. This organization in a contingency table can help us answer various probability questions based on independent events, mutually exclusive events and conditional probabilities. For example, if we had a table with vehicle speeds and vehicle information, we could answer questions such as: Given a person was in a 50 mile per hour zone, what is the probability they were speeding? What is the probability that a person was speeding and driving a motorcycle? What is the probability a person was speeding or driving a sports car?
