Fault Since 1857, Parkfield, California, has had a major earthquake on the average of once every 22 years. Explain why a Poisson probability distribution would be a good choice for r = number of earthquakes in a given time interval. Compute the probability of at least one major earthquake in the next 22 years. Round λ to the nearest hundredth, and use a calculator. Compute the probability that there will be no major earthquake in the next 22 years. Round λ to the nearest hundredth, and use a calculator.

Adam teaches a class on probability calculus. Students have noticed that Adam is generally 3 minutes late, and the irregularity with which he appears in class deviates from the average by 7 minutes. Assuming that the instructor's appearance time in a probability calculus class has a normal distribution, determine the probability that the class will not be held (the instructor will be more than 15 min late). Duration of the class is 90 minutes.
