A meal pack has 3 main dishes, 4 drinks, and 2 dessert options. How many packs can be made by choosing one item from each category?

Answer and explanation

Correct answer: 24 packs

The governing principle is the fundamental principle of counting: when a complete choice consists of independent stages, and the stages have m, n, and p possibilities, the total number of outcomes is m × n × p. Here there are 3 choices for the main dish, 4 choices for the drink, and 2 choices for the dessert. Therefore, total meal packs = 3 × 4 × 2 = 24. Each main dish can be paired with all 4 drinks and both desserts, so no combinations are omitted or repeated. Hence option B is correct. Adding the choices would not represent selecting one item from every category; 9, 12, and 18 arise from inappropriate operations.
