To find the number of ways John can choose her introductory package, we need to multiply the number of options in each category.
First, let's identify the number of options in each category:
- In the rock category, there are 12 options.
- In the alternative category, there are 10 options.
- In the country category, there are 7 options.
- In the classical category, there are 5 options.
To find the total number of ways John can choose her introductory package, we need to multiply these numbers together:
12 rock options * 10 alternative options * 7 country options * 5 classical options = 12 * 10 * 7 * 5 = 3,000.
Therefore, there are 3,000 ways John can choose her introductory package.
