Probability Distribution Function (PDF) for a Discrete Random Variable · Exercise 13
Javier volunteers in community events each month. He does not do more than five events in a month. He attends exactly five events 35 percent of the time, four events 25 percent of the time, three events 20 percent of the time, two events 10 percent of the time, one event 5 percent of the time, and no events 5 percent of the time.
Define the random variable X.
