Answer :
An estimated 69.8% chance exists that 15 or more out of 20 planes will arrive on schedule.
The 20 flights were simulated 25 times in this scenario, and the outcomes were 11, 15, 14, 8, 17, 14, 16, 15, 17, 15, 9, 13, 16, 12, 18, 14, 16, 13, 15, 16, 14, 18, and 9. These figures add up to a total of 349 on-time departures out of 500 simulated departures.
It might be difficult to determine the likelihood that 15 or more aircraft out of 20 will depart on time. Thankfully, several approaches may be utilized to gauge the chance. One such approach is to simulate the issue under consideration several times, analyze the results, and then determine an estimated likelihood.
Therefore, an estimated 69.8% chance exists that 15 or more out of 20 planes will arrive on schedule.
