Suppose the flight attendant’s total duration of employment is 20 years. What is the probability that he/she encounters at least 10 IFMs on his/her flights over a 20-year period? Make the same assumptions as in Problem 4.96.

The more significant IFMs result in an aircraft being forced to land in an airport other than its original destination due to the medical emergency (referred to as an aircraft diversion or DIV). Suppose that 875 out of the 11,920 IFMs (7.3%) resulted in a DIV.

Emergency Medicine
A study was performed concerning medical emergencies on commercial airline flights (Peterson, et al., [16]). A database was constructed based on calls to a medical communications center from 5 domestic and international airlines representing approximately 10% of global passenger flight volume from January 1, 2008 to October 31, 2010. There were 11,920 in-flight medical emergencies (IFM) among 7,198,118 flights during the study period. Assume for this entire problem that there is at most 1 IFM per flight.
