Probability of Watching TV

The video tutorial explains how to solve a basic probability question by constructing and filling a probability table. It involves understanding joint and marginal probabilities, and using these to answer specific questions about the likelihood of events, such as whether both a husband and wife are watching HBO. The tutorial emphasizes the importance of organizing information in a table to simplify problem-solving.
