Final answer:
Nonexcludable goods or services are those that cannot be withheld from individuals and are typically available to everyone without direct payment. Police protection, roads, and primary education are examples of nonexcludable services, whereas streaming music and cell phone services are not, as they can exclude non-payers.
Step-by-step explanation:
In economics, nonexcludable goods or services are those that cannot reasonably be withheld from individuals once they have been provided. It's impossible or highly impractical to charge users for their consumption of these goods, and thus they are available to everyone regardless of whether an individual contributes to their provision.
The options provided present a mixture of goods and services, but not all are nonexcludable:
- Police protection is considered a nonexcludable service because once provided, you cannot exclude certain individuals from being protected by the police.
- Roads are typically nonexcludable as they are provided by the government and available for public use without directly charging users each time they are used.
- Primary education in many countries is nonexcludable as it is often provided by the government without direct cost to the student or family.
On the other hand, services like streaming music or cell phone service are typically excludable because providers can prevent non-paying customers from accessing them.
