medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate risk for both features
Feature 1 risk = 5 x 1 = 5; Feature 2 risk = 2 x 4 = 8.Step 2: Compare risk values
Feature 2 has higher risk (8) and should be tested first.Final Answer:
Feature with Impact=2 and Likelihood=4 -> Option BQuick Check:
Higher risk = Feature 2 (8) [OK]
Quick Trick: Multiply impact and likelihood to compare risks [OK]
Common Mistakes:
- Choosing feature with higher impact only
- Ignoring likelihood in calculation
- Assuming equal risk without calculation
