A gift pack has 5 cover options, 2 ribbon options, and 3 card options. In how many ways can one complete pack be made?

Answer and explanation

Correct answer: 30

The governing concept is the multiplication principle for a complete arrangement with several independent choices. A complete gift pack requires one cover, one ribbon, and one card. There are 5 choices for the cover; for each of those, 2 ribbon choices remain; and for each resulting pair, 3 card choices are possible. Therefore the total number of packs is 5 × 2 × 3 = 30. Option D is correct. The value 10 counts only covers and ribbons, leaving cards unselected. The value 20 does not represent all three stages, and 25 incorrectly treats the choices as though two categories each had five options. Since every pack includes one item from each category, the choices are consecutive and must be multiplied rather than added.
