Final answer:
Police protection, roads, and primary education are examples of nonexcludable services because they are available to all members of a community and individuals cannot be easily excluded from using them. Streaming music and cell phone service, conversely, are excludable because access can be restricted to paying customers.
Step-by-step explanation:
The student has asked which of the following goods or services are nonexcludable: police protection, streaming music from satellite transmission programs, roads, primary education, or cell phone service. Nonexcludable goods or services are those that individuals cannot be effectively excluded from using, and which are typically available to all members of society. In this context, nonexcludable services include police protection, which is provided to an entire community without directly charging each individual; roads, which are typically available for public use by anyone; and primary education, which is often provided by the government to children without a direct fee. Conversely, streaming music from satellite transmission programs and cell phone service are both excludable, as they can be restricted to only those who have paid for the service.
