Probability Distribution Function (PDF) for a Discrete Random Variable · Exercise 11
Ellen has music practice three days a week. She practices for all of the three days 85 percent of the time, two days 8 percent of the time, one day 4 percent of the time, and no days 3 percent of the time. One week is selected at random.
