A student has to choose one chapter from (5) chapters and then one question from (6) questions of the chosen chapter. How many question selections are possible?

Answer and explanation

Correct answer: (30) selections

The governing concept is the fundamental principle of counting: when a choice is made in successive stages, and every choice at one stage can be followed by every choice at the next stage, the numbers of choices are multiplied. The student first has 5 independent chapter choices. After any one chapter is selected, there are 6 question choices within that chapter. Therefore, the total number of chapter-question pairs is 5 × 6 = 30. Option D is correct because each selection is identified by both its chapter and its question. Adding 5 and 6 would count stages rather than complete selections, while 25 and 36 do not represent the required product.
