Final answer:
The county commissioner's court usually comprises a county judge and four county commissioners, where they work together to manage the administrative responsibilities of the county.
Step-by-step explanation:
The composition of the county commissioner's court typically consists of a county judge and four county commissioners. This is substantiated by the fact that county governments usually operate under a commission system, where an elected body performs legislative and executive functions, such as adopting budgets, passing county resolutions, and overseeing the hiring and firing of other county officials. The county judge typically presides over this court, while the commissioners represent different districts or areas within the county, collaborating to manage county affairs.
