Probability Distribution of a Discrete Random Variable

  • The probability distribution for a discrete random variable lists the possible values it can take on and the corresponding probabilities.

  • For each value the discrete random variable can take on, the probability must be between 0 and 1.

  • The sum of the probabilities for all values the discrete random variable can take on must be equal to 1.
