One study examined the relationship between survival of patients with coronaryheart disease and pet ownership. Each of 92 patients was classified as having a pet or notby whether they survived for one year. The researchers suspected that having a pet mightbe connected to the patient status. Here are the data:Pet OwnershipPatient StatusNoYesAlive2850Dead113Total3953a. Assuming the patient is still alive, what is the probability that he owns a pet? Is thisa joint, marginal or conditional probability?5078=.6410, conditionalb.
