Answer:
Bob can pay to support his local public radio station, which depends on donations to be as effective as possible. Bob listens to the radio station several hours per day but never donates since he suspects that other people will donate enough to keep the station on the air.
Jim is working on a group project for a class in which he wants a high grade. However, since the grades are assigned to the group as a whole and he knows that the other group members will pick up most of the extra work, Jim calls in sick and plays video games on his Dream Station 64
Step-by-step explanation:
Free riding is a form of market failure where a person who benefits from a good or service doesn't pay for it.
Bob enjoys the radio but doesn't support it and Jim doesn't participate in the group project but expects to earn a good grade; these are examples of free riding.
Karl doesn't benefit from the street light and doesn't pay; hence, he is not free riding.
I hope my answer helps you.
