Final answer:
Using the Law of Detachment in logic, if the premise 'one gets a ticket when driving 20 miles above the speed limit and getting pulled over' is true, and Charles did just that, we conclude that definitely, Charles will get a ticket.
Step-by-step explanation:
According to the Law of Detachment, which is a principle in logic and mathematics used in deductive reasoning, we can draw a specific conclusion based on a generalization and a related fact that is true. In this case, if the statement 'If anyone goes 20 miles above the speed limit and gets pulled over, then they will get a ticket' is true and we know that 'Charles went over the speed limit by 20 miles and gets pulled over', then according to the Law of Detachment, we can conclude that Charles will definitely get a ticket.
