When confronted with an in-flight medical emergency, pilots and crew can consult staff physicians at MedAire, an emergency facility in Tempe, Arizona. If MedAire is called, there is a 4.8 percent chance that the flight will be diverted for an immediate landing. (a) If MedAire is called 8,465 times (as it was in 2002), what is the expected number of diversions? (b) What is the probability of at least 400 diversions? (c) Fewer than 450 diversions?
