B
A
C D
If each variable can take 5 different values, what is the minimum number of parameters needed to
represent the conditional probabilities of each Bayesian network?
(Hint: P(A) on the left requires only four parameters, since the fifth, P(A = 5) = 1-P(A= 1)-P(A =
2) - P(A=3) - P(A = 4), can be recovered from the other four.)
