The sum of all possible values of \( b \) is \(\boxed{6}\).<thinkQuestion: A seismologist analyzing earthquake patterns observes that tremors occur on three fault lines—A, B, and C—with probabilities $ \frac{1}{5} $, $ \frac{1}{6} $, and $ \frac{1}{10} $ respectively on any given day. Assuming independence, what is the probability that exactly one fault line experiences tremors on a randomly selected day?
