- Suppose 24 patients undergo open heart surgery at a certain hospital whose mortality rate is 0.15. If V is the number of patients who die within the first 30 days of undergoing open heart surgery, what’s the expected number of patients that die within the first 30 days of undergoing open heart surgery?
V ~ B(24, 0.15)
E(V) = 24(0.15) = 3.6
