Final answer:
The majority of cases are tried in state courts, which have jurisdiction over a wide range of legal issues, in contrast to federal courts that hear cases with specific federal concerns.
Step-by-step explanation:
The vast majority of all cases are tried in state courts. This includes the initial trial phase for a wide array of legal matters such as traffic violations, divorce proceedings, and serious criminal offenses like robbery, and murder. State courts have broad jurisdiction, covering most crimes and civil matters. The federal courts, in contrast, handle cases with specific federal issues, such as those involving foreign governments, patent issues, and interstate disputes. While federal courts include the U.S. district courts, appellate courts, and the U.S. Supreme Court, they see far fewer cases compared to state courts, with approximately 90 percent of all U.S. court cases being adjudicated at the state level.
