An online test has 4 subjects, 5 difficulty levels, and 2 language options. How many test settings are possible?

Answer and explanation

Correct answer: 40 settings

The governing concept is the multiplication principle for independent selections. One test setting is formed by choosing one subject, one difficulty level, and one language. There are 4 choices for the subject, 5 choices for the difficulty level, and 2 choices for the language. Since each subject can be paired with every difficulty level and either language, the total is 4 × 5 × 2 = 20 × 2 = 40 settings. Thus option B is correct. The value 20 omits the language choice, 11 incorrectly adds the three numbers, and 80 includes an extra factor not present in the question. The categories are chosen together, so multiplication rather than addition is required.
