Probability Distribution Function (PDF) for a Discrete Random Variable · Exercise 16
Javier volunteers in community events each month. He does not do more than five events in a month. He attends exactly five events 35% of the time, four events 25% of the time, three events 20% of the time, two events 10% of the time, one event 5% of the time, and no events 5% of the time.
Find the probability that Javier volunteers for less than three events each month. P(x < 3) = _______
