A sweet box allows choosing from (8) sweet types and (2) box sizes. In how many ways can one sweet type and one size be chosen?

Answer and explanation

Correct answer: 16

There are 8 choices for the sweet type, and for each selected type there are 2 choices of box size. By the fundamental principle of counting, the total number of choices is \(8\times2=16\). The options 10, 8, and 12 do not correctly multiply the two independent choices. Exam tip: Multiply the number of choices when successive selections are independent.
