A digital poster has (4) fonts (6) colors and (2) background textures. How many poster styles are possible?

Answer and explanation

Correct answer: 48

To form one poster style, choose one of 4 fonts, one of 6 colours, and one of 2 background textures. By the fundamental principle of counting, the total number of styles is \(4 \times 6 \times 2=48\). Option 24 misses the multiplication by the 2 texture choices. Exam tip: Multiply the numbers of choices when every choice at one stage can be combined with every choice at the next stage.
