Question
Below is a tree diagram representing a diagnostic or screening test. On this diagram, what is the probability assigned to the top branch linking "feature" with "positive"? **Diagram Details:** 1. **Initial Node**: - Individual from a specific population 2. **First Branch**: - Splits into two paths: - **Feature** - **No feature** 3. **Second Branch**: - Each path from the first branch splits further: - **Feature** splits into: - Positive - Negative - **No feature** splits into: - Positive - Negative **Question:** What is the probability related to the top branch that links "feature" with "positive"? **Options:** - ○ P(positive|feature) - ○ P(feature) - ○ P(feature|positive) - ○ P(feature and positive) - ○ P(feature or positive) - ○ P(positive)
