Question 1
A restaurant offers 5 appetizers, 6 main courses, and 5 desserts. How many different meal combinations can be made?
Step-by-Step Solution:
Concept: This problem uses the Fundamental Counting Principle (Multiplication Rule). When making sequential independent choices, multiply the number of options at each step.
Analysis:
- First choice: 5 options
- Second choice: 6 options
- Third choice: 5 options
Calculation:
Total ways = 5 × 6 × 5 = 150
Key Principle: For independent sequential events, multiply the number of choices at each stage.
Verification: Each of the 5 first choices can be paired with each of the 6 second choices (5×6=30), and each of these can be combined with any of the 5 third choices.
