medium📝 Debug Q6 of 15
Step-by-Step Solution
Solution:
Step 1: Understand difference in formulas
Addition sums values, multiplication combines impact and likelihood more strongly.Step 2: Effect on risk value
Addition underestimates risk when both factors are high compared to multiplication.Final Answer:
Risk calculation will underestimate combined risk -> Option CQuick Check:
Using addition underestimates risk [OK]
Quick Trick: Use multiplication, not addition, for risk calculation [OK]
Common Mistakes:
- Thinking addition overestimates risk
- Assuming both formulas are equal
- Confusing syntax error with logic error
