Final answer:
The default number of agents per page on an assignment workbench typically depends on the system used and can often be customized. Exact numbers like 10, 20, or 50 agents per page are common defaults, but one should verify this in the application's settings or documentation.
Step-by-step explanation:
The default setting for the number of agents per page on the assignment workbench typically depends on the specific application or platform being used. However, if we're referring to a standard or commonly used system, it often sets a default value to display a certain number of items per page, such as 10, 20, or 50 agents.
Since this setting can vary, it's important to check the system or software documentation or settings menu to find the exact number. Furthermore, users usually have the option to customize this setting according to their preferences or needs for the workflow.
