**Inspection Process for Defective Items** Before leaving the factory, items undergo inspection to determine if they are defective. Here's how the process works: - **Defective Items:** - If an item is defective, there's a **90% probability** it will be labeled as negative (-). - **Non-Defective Items:** - If an item is not defective, there's a **5% probability** it will incorrectly be labeled as negative (-). **Notation:** - Let \( D \) represent the event that an item is defective. - Let \(-\) denote the event where an item is labeled as negative. - Items have a **10% probability** of being defective. **Events:** - \( D \) = Defective - \( D^c \) = Not defective - \(-\) = Negative - \(-^c\) (or \(+\)) = Not negative (Positive) This process helps in deciding whether items are fit for use.
