This concept shows how AI handles inputs and produces outputs with varying confidence levels. Sometimes AI is confident and correct, sometimes confident but wrong, and sometimes uncertain. When AI is uncertain, it suggests human review. The execution table traces five examples showing inputs, outputs, confidence, correctness, and actions. Variable tracking shows how these values change step by step. Key moments clarify common confusions about AI confidence and error handling. The visual quiz tests understanding of confidence levels and when human review is needed. The snapshot summarizes the main ideas for quick recall.
