Q. Annie's little sister wants help getting her bicycle ready for a parade. She can choose among

2

colors of handlebar streamers and

4

different bicycle bells. How many different ways can Annie's little sister decorate her bicycle?

\newline

_____ ways

Identify Choices: Identify the number of choices for each type of decoration. $\newline$ Annie's sister can choose from $2$ colors of handlebar streamers and $4$ different bicycle bells.
Use Counting Principle: Use the fundamental counting principle. $\newline$ To find the total number of different ways to decorate the bicycle, multiply the number of choices for handlebar streamers by the number of choices for bicycle bells. $\newline$ Total ways $= \text{Number of streamer choices} \times \text{Number of bell choices}$ $\newline$ Total ways $= 2 \times 4$
Perform Multiplication: Perform the multiplication to find the total number of different ways. $\newline$ Total ways = $2 \times 4 = 8$
