Final answer:
The statement "employee (1,1) works for (1,N) department is equivalent to: employee (N) works for 1 department" describes equal participation.
Step-by-step explanation:
According to the given question, the statement "employee (1,1) works for (1,N) department is equivalent to: employee (N) works for 1 department" describes equal participation.
This is because in both cases, there is no distinction among the participants. In the first case, every employee works for at least one department, and in the second case, every department is staffed by at least one employee. Therefore, the participation is equal.
This concept can be applied in various contexts, such as assigning tasks or distributing resources equally among different entities.
