Extracted text: #20 Earthquakes: San Andreas Fault Since 1857, Parkfield, California, has had a major earthquake on the average of once every 22 years. (a) Explain why a Poisson probability distribution would be a good choice for r= number of earthquakes in a given time interval. (b) Compute the probability of at least one major earthquake in the next 22 years. Round 2 to the nearest hundredth, and use a calculator. (c) Compute the probability that there will be no major earthquake in the next 22 years. Round 2 to the nearest hundredth, and use a calculator. (d) Compute the probability of at least one major earthquake in the next 50 years. Round 2 to the nearest hundredth, and use a calculator. (e) Compute the probability of no major earthquake in the next 50 years. Round 2 to the nearest hundredth, and use a calculator.
