The video tutorial explains how to determine the number of ways to complete a true-false test with eight questions using the counting principle. Each question is treated as an independent event with two possible outcomes: true or false. By modeling the problem as a sequence of independent events, the total number of ways to complete the test is calculated as 2^8, resulting in 256 different ways. The tutorial concludes with a brief summary of the solution.
