A party store offers small balloons and large balloons. You can choose from pink, blue, green, and yellow balloons. You can choose from silver, gold, and white ribbons. Use the counting principle to find the number of different ways you can choose a balloon with a ribbon.
There are 2 choices for the size of the balloon (small or large) and 3 choices for the color of the ribbon (silver, gold, or white). Therefore, using the counting principle, there are:
2 x 3 = 6 different ways to choose a balloon with a ribbon.
