An AI uses a threshold of 70% confidence to decide if it should answer or say 'I don't know.' If it outputs an answer with 65% confidence, what should it do to handle uncertainty properly?
AIgnore the confidence score and guess randomly
BProvide the answer confidently anyway
CSay 'I don't know' because confidence is below threshold
DAlways refuse to answer regardless of confidence
Step-by-Step Solution
Solution:
  1. Step 1: Understand confidence threshold use

    The threshold defines when AI is confident enough to answer.
  2. Step 2: Apply threshold to given confidence

    65% is below 70%, so AI should not answer confidently but express uncertainty.
  3. Final Answer:

    Say 'I don't know' because confidence is below threshold -> Option C
  4. Quick Check:

    Confidence below threshold = express uncertainty [OK]
Quick Trick: Below threshold confidence means say 'I don't know' [OK]
Common Mistakes:
MISTAKES
  • Ignoring threshold and answering anyway
  • Guessing randomly without indication
  • Refusing to answer even when confident
