A cafe has 3 types of tea, 4 types of coffee, and 2 types of juice. In how many ways can exactly one drink be chosen?

Answer and explanation

Correct answer: 9

The governing concept is the addition rule of counting, which applies when exactly one choice is made from mutually exclusive groups. A customer chooses either one tea, one coffee, or one juice; the choices are alternatives rather than simultaneous selections. Therefore, the total number of possible drinks is 3 + 4 + 2 = 9. Option C is correct because it counts every available drink exactly once. Multiplication would be appropriate only if the customer had to choose one item from each category, which would give 3 × 4 × 2 = 24, but that is not what the question asks. Thus, options A and B use an inappropriate multiplication or partial count, while option D omits two choices.
