Three soccer teams A, B, and C, play each other once. Each match is between two teams, and can be won, drawn, or lost. Each team has a fixed, unknown degree of quality an integer ranging from 0 to 3and the outcome of a match depends probabilistically on the difference in quality between the two teams. a. Construct a relational probability model to describe this domain, and suggest numerical values for all the necessary probability distributions. b. Construct the equivalent Bayesian network for the three matches. c. Suppose that in the first two matches A beats B and draws with C. Using an exact inference algorithm of your choice, compute the posterior distribution for the outcome of the third match.
