CategoricalDistribution

CategoricalDistribution[{c1,c2,…}] represents a uniform categorical distribution over classes c1, c2, etc.

CategoricalDistribution[{c1,c2,…},{w1,w2,…}] represents a categorical distribution over classes ci with weights wi.

CategoricalDistribution[{{a1,a2,…},{b1,b2,…},…}] represents a uniform multivariate categorical distribution over domain {a1,a2,…}×{b1,b2,…}×….

CategoricalDistribution[domain,weights] uses the array weights to define probabilities over each element of the domain.
