Final answer:
Without access to the specific contract, providing a correct answer to the question about IROP and non-IROP wait times at the airport is not possible. The information about airplane arrivals, departures, and probabilities does not relate to the nuances of business contract terms.
Step-by-step explanation:
The subject in question revolves around understanding contract stipulations related to airport wait times in different operational scenarios, specifically during Irregular Operations (IROP) and non-IROP conditions. However, without the specific contract terms provided within the question, it's impossible to determine the correct answer accurately. Thus, to answer the question 'Per the contract, the company can have you stay at the airport for how many minutes in an IROP and for how many minutes without an IROP declared?', one would need to reference the actual contract in question.
The provided information a) through d), does not correspond to the details necessary to answer the question. It relates to air traffic statistics, specifically the number of airplane arrivals and departures per hour and the probabilities associated with these events. Calculating these probabilities typically falls under the domain of mathematics, particularly statistics and probability theory, rather than business contract specifics. Nevertheless, the answer requires knowledge of business procedures and contract details rather than statistical analysis.
