Question 1
A student has 6 shirts, 6 pants, and 3 pairs of shoes. How many different outfits 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: 6 options
- Second choice: 6 options
- Third choice: 3 options
Calculation:
Total ways = 6 × 6 × 3 = 108
Key Principle: For independent sequential events, multiply the number of choices at each stage.
Verification: Each of the 6 first choices can be paired with each of the 6 second choices (6×6=36), and each of these can be combined with any of the 3 third choices.
