Final answer:
The ability to order only wings or only drums depends on the policies and offerings of the restaurant or food service provider, and cannot be determined without specific context.
Step-by-step explanation:
The question about whether a customer can order only wings or only drums is related to business, specifically to the offerings and policies of restaurants or food services. Determining if an establishment allows for customization of orders is essential for customer satisfaction and business operations. In general, the ability for customers to order custom chicken orders would depend on the specific restaurant or service provider's menu options and their flexibility in fulfilling customer requests.
For example, some establishments might have a fixed menu and may not accommodate individual preferences, meaning they serve chicken as an assortment of pieces including both wings and drums. Others may offer specialized orders, allowing customers to select their preferred type of chicken piece—be it wings-only or drums-only. Without a specific context or policy provided, it is difficult to provide a definitive answer.
Calculating the probability of events like getting a piece of chicken that is not 21 oz. or avoiding a chicken breast and a pork chop are separate issues that would require more context to accurately assess, such as a menu, pricing, and inventory practices.
