Q. Katy's little sister wants help getting her bicycle ready for a parade. She can choose among 4 colors of handlebar streamers and 3 different bicycle bells. How many different ways can Katy's little sister decorate her bicycle?_______ ways
Determine Choices Separately: To determine the total number of different ways Katy's little sister can decorate her bicycle, we need to consider the choices for handlebar streamers and bicycle bells separately. Since she can choose from 4 colors of handlebar streamers and 3 different bicycle bells, we can use the fundamental counting principle. This principle states that if there are m ways to do one thing, and n ways to do another, then there are m×n ways to do both.
Calculate Total Combinations: Calculate the total number of combinations by multiplying the number of choices for handlebar streamers by the number of choices for bicycle bells.4 (colors of handlebar streamers) ∗3 (different bicycle bells) = 12 different ways.
Check Calculation: Check the calculation for any mathematical errors. The multiplication is straightforward, and 4 times 3 does indeed equal 12.
