Consider the discrete random variable with the following distribution.

  1. Explain why this is a valid probability model.

    In a valid probability model, the sum of the probabilities of the outcomes must be . Also, the probability of each outcome must be between and , inclusive.

  2. Create a relative frequency histogram for this probability distribution.

  3. Calculate the expected value of .
