• AKA: Nominal RV Function.
• Context:
  • It can range from being a Binary Random Variable to being a Multinomial Random Variable.
  • It can be represented by a Categorical Probability Function.
  • …
• Example(s):
  • a Random Variable that represents a Dice Roll Experiment.
  • …
• Counter-Example(s):
  • any Continuous Random Variable, such as one that represents a Lifetime Experiment.
  • any Ordinal Random Variable.
