Question

According to an article in The Sacramento Bee (www.sacbee.com/2011/08/04/3816872/medicareprescription- premiums.html), approximately 10% of Medicare beneficiaries lack a prescription drug care plan. Suppose that a town in Florida has 2384 residents who are Medicare beneficiaries, and 216 of them do not have a prescription drug care plan. If one of the Medicare beneficiaries is chosen at random from this town, what is the probability that this person has a prescription drug care plan? What is the probability that this person does not have a prescription drug care plan? Do these probabilities add up to 1.0? If yes, why? If no, why not?
