Question

roy builds custom - made bicycles. the frames come in 10 sizes and 2 colors. how many different bicycles is it possible for roy to build? bicycles

Explanation:

Step1: Apply the counting principle

The counting principle states that if there are \(m\) ways to do one thing and \(n\) ways to do another thing, then there are \(m\times n\) ways to do both things. Here, \(m = 10\) (number of sizes) and \(n=2\) (number of colors).

Step2: Calculate the number of bicycles

We calculate \(10\times2\).

$$10\times2=20$$

Answer:

20
