Figure 2.5. A fault tree example

A fault tree example (Probability equations omitted). The tree progresses from: (1) Top Event to (2) OR symbol, which splits in two; (3) One branch (right) leads to Minimal Cut Set 2: Basic Failure #3; (4) Second branch (left) leads to AND symbol where tree splits in two again, leading to Minimal Cut Set 1: Basic Failure #1 and Basic Failure #2.

Note: P = probability, F = basic failure.
