For a recent 41-year period, there were 5,469 major earthquakes; these are earthquakes measuring at least 6.0 on the richter scale in the world (based on u. s. geological survey data). write down the formula for the probability that the number of major earthquakes in 2016 will be between 131 and 133 inclusive. or just tell me, when given a range of events between two numbers with x between them, how do you find x to use for the poisson distribution formula?
