A student has to choose one each from (2) bags (6) pens and (3) notebooks. How many total selections are possible?

Answer and explanation

Correct answer: (36) selections

The direct answer is option D: 36 selections. The student chooses one bag, one pen, and one notebook. These are three independent stages. There are 2 bag choices; for each bag there are 6 pen choices; for each bag-and-pen pair there are 3 notebook choices. Therefore the multiplication principle gives 2 × 6 × 3 = 12 × 3 = 36. Option D is correct. Option A, 11, is obtained by adding the numbers, but addition does not count complete selections containing one item from every category. Option B, 24, misses one factor or uses an incomplete calculation. Option C, 18, is also not the product of all three choice counts. The total is not the number of objects but the number of possible complete triples. Memory cue: for one choice from every independent group, multiply every group size once.
