A photo filter app has (3) filters, (4) frames and (5) sticker options. How many total looks are possible by choosing one each?

Answer and explanation

Correct answer: (60) looks

The fundamental principle of counting applies because each final look is created by making one independent choice from each of three groups. There are 3 filter choices, 4 frame choices and 5 sticker choices. First, a filter and frame can be paired in 3 × 4 = 12 ways. Every one of these 12 pairs can be combined with any of the 5 stickers, giving 12 × 5 = 60 looks. Equivalently, the count is 3 × 4 × 5 = 60. Therefore option A is correct. Option B stops after two features, option C uses only 3 × ? Actually 20 omits one factor, and option D is an incorrect product. All three selections are required for a complete look.
