The Minneapolis Heart Institute conducted a study to determine the benefit of follow-up care for patients discharged from a hospital after a heart attack. Out of 2060 patients, 1070 returned

for follow-up treatment and 990 did not. Within 24 months, 29 of the patients receiving follow-up treatment died, and 14 of the patients not receiving follow-up treatment died. What is the probability of a patient surviving within 24 months of being discharged after a heart attack? Given that a patient survived, what is the probability that he had NOT received follow-up treatment?
