An online quiz has (5) subject categories and (7) marking schemes. In how many ways can one category and one scheme be chosen?

Answer and explanation

Correct answer: 35

There are 5 choices for the subject category, and for each chosen category there are 7 choices for the marking scheme. By the fundamental principle of counting, the total number of choices is \(5 \times 7=35\). Option 49 comes from \(7 \times 7\), but there are only 5 categories. Exam tip: multiply the numbers of choices when independent selections are made in sequence.
