Final answer:
The question seems to involve geometric properties and Kirchhoff's laws. Without the provided diagrams, we cannot ascertain which statement is true.
Step-by-step explanation:
The question appears to be related to geometric properties and their application to parallel lines and angles created by them. However, the question references diagrams that are not provided in the context, making it impossible to determine which statement is true without additional information. As a tutor, I would need the actual figure to answer accurately.
The reference to currents (I1, I2, I3) suggests a problem involving Kirchhoff's laws in physics, specifically electrical circuits, and the statements given are related to probabilities and independence between events, which is a topic in statistics, a branch of mathematics.
For a comprehensive response, the relevant diagram or figure would be essential. If there's further clarification on the specific question or additional context such as the diagram, I can provide a detailed answer.
