Use the following information to answer the next five exercises:
Javier volunteers 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.
13. Define the random variable X.
14. What values does x take on?
15. Construct a PDF table.
16. Find the probability that Javier volunteers for less than three events each month. P(x 3) = _
17. Find the probability that Javier volunteers for at least one event each month. P(x > 0) =
4.2 Mean or Expected Value and Standard Deviation
18. Complete the expected value table.
