Coronary bypass surgery: A healthcare agency reported that 87% of people who had coronary bypass surgery in 2008 were over the age of 65. Fifteen coronary bypass patients are sampled. Part 1 of 4 (a) What is the probability that exactly 10 of them are over the age of 657 Round the answer to four decimal places. The probability that exactly 10 of them are over the age of 65 is Part 2 of 4 Part 3 of 4 X (b) What is the probability that more than 11 are over the age of 657 Round the answer to four decimal places. The probability that more than 11 are over the age of 65 is X 5 15 (c) What is the probability that fewer than 9 are over the age of 657 Round the answer to four decimal places.
