solve the problem by applying the fundamental counting principal with two groups of items.

Shaun is joining a music club. as part of ther 4-cd introductory package she can choose from 12 rock, 10 alternative, 7 country, and 5 classical. if Shaun choose one selection from each category, how many ways can she choose her introductory package?

Andrews's mother always makes his lunch for him. She packs 1 brown-bread sandwich, 1 white-sandwich, 1fruit item and 1 dessert item. Andrews likes ham, cheese, salami, chicken, turkey, and jam as sandwich fillings. He likes apples, grapes bananas and pears and he likes Oreo cookie chocolate cake, fudge butterscotch pudding and ohenry clusters for dessert. How many lunches can Andrew have if his mother puts different filling each sandwich

To solve this problem using the Fundamental Counting Principle, we need to multiply the number of choices in each category.

1. First, we have 12 choices for the rock CD.
2. Then, we have 10 choices for the alternative CD.
3. Next, we have 7 choices for the country CD.
4. Finally, we have 5 choices for the classical CD.

To determine the total number of ways Shaun can choose her introductory package, we multiply the number of choices in each category:

12 choices × 10 choices × 7 choices × 5 choices = 4,200 ways

Therefore, Shaun can choose her introductory package in 4,200 different ways.
