In gift wrapping department, a customer can choose from x different papers, y different ribbons, and z different greeting cards. There are 160 different paper, ribbon, and greeting card combinations possible. List three of the possible combinations.

What forumula are used? Don't understand this problem. Need help.
Thanks.

To find the number of possible combinations in this gift-wrapping problem, we will use the fundamental principle of counting, also known as the multiplication principle.

The multiplication principle states that if there are x ways to do one thing and y ways to do another thing, then there are x * y ways to do both things together.

In the case of the gift wrapping department, there are x options for paper, y options for ribbons, and z options for greeting cards. To find the total number of combinations, we multiply these numbers together: x * y * z.

In this problem, we are given that there are 160 different combinations of paper, ribbon, and greeting card. However, we are not provided with specific values for x, y, and z. Therefore, we cannot provide specific combinations.

However, I can help you understand the concept better through an example. Let's say there are 4 different papers (x = 4), 5 different ribbons (y = 5), and 6 different greeting cards (z = 6). Using the multiplication principle, the total number of combinations would be: 4 * 5 * 6 = 120 combinations.

Three possible combinations could be:
1. Paper 1, Ribbon 2, Greeting Card 3
2. Paper 3, Ribbon 4, Greeting Card 2
3. Paper 2, Ribbon 1, Greeting Card 5

Remember, these combinations are just for illustration purposes. The actual combinations will vary based on the specific values of x, y, and z given in the problem.

If you have the values for x, y, and z, you can substitute them into the multiplication formula (x * y * z) to find the total number of combinations in this gift wrapping problem.
