Question

4. In a recent period of 100 years, there were 93 major earthquakes in the world. Assuming that Poisson distribution is a suitable model, find the mean number of major earthquakes per year. Then find the probability that there are at least 2 earthquakes in a randomly selected year. Show all your work.

Step 1

Given that there were 93 major earthquakes in 100 years, the mean number of earthquakes per year can be calculated as: Mean = Total number of earthquakes / Total number of years Mean = 93 / 100 Mean = 0.93 earthquakes per year Show more…
