The number of earthquake tremors in a 12-month period appears to be distributed as a Poisson random variable with a mean of 6.Assume the number of tremors from one 12-month period is independent of the number in the next 12-month period. What is the probablity that there are no tremors in a 1-month period? What is the probability tha there are more than 5 tremors in a 6-month period?
