Final answer:
The percentage rate needed to pass the course in both the driving and written test depends on the course guidelines and may vary, though common standards are usually around 75% to 90%.
Step-by-step explanation:
To answer the question regarding the percentage rate needed to successfully complete a course in both the driving and written test, you must check the specific regulations or guidelines provided by the course or institution. Generally, courses have a set minimum percentage that students must achieve to pass, but this may vary. If it's a standard like most driving tests, one might speculate it to be around 75% to 90%, but this is not certain without the proper context. It's important to look at the course materials or ask the instructor directly for accurate information.
As you're looking at questions related to probability and percentages, these topics are rooted in Mathematics, particularly the field of statistics.
