hard📝 Application Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Identify boundary and just outside values for age 18 to 60
Boundaries are 18 (min) and 60 (max). Just outside are 17 (below min) and 61 (above max).Step 2: Check which option includes all boundaries and just outside values
17, 18, 60, 61 includes 17, 18, 60, and 61, covering all required boundary and just outside values.Final Answer:
17, 18, 60, 61 -> Option AQuick Check:
Test min, max, and just outside values for full coverage [OK]
Quick Trick: Always include min, max, and one value outside each boundary [OK]
Common Mistakes:
- Missing just outside boundary values
- Testing only valid inputs inside range
- Confusing boundary values with random inputs
