A product has (5) models (4) colors (6) storage options and (2) warranty plans. How many product options are possible?

Answer and explanation

Correct answer: 240

For each model, one of 4 colours, one of 6 storage options, and one of 2 warranty plans can be selected. By the fundamental principle of counting, the total number of options is \(5 \times 4 \times 6 \times 2=240\). Hence, option C is correct. A result such as 360 would come from incorrect multiplication or double-counting a choice. Exam tip: When choices are made in independent stages, multiply the number of choices at each stage.
