In 2016, the San Francisco Chronicle reported that there is approximately a 72% probability of a major earthquake in the San Francisco Bay region before the year 2043. An accompanying map showed 6 major faults in the area and listed the probabilities of a big quake on each of these faults as being 22%, 8%, 6%, 33%, 16%, and 26%. Assuming big quakes on these faults are independent events, do you agree with the ~ 72% estimate for the probability of a "big one" in the Bay Area? Explain your answer
