The world's most active above sea level volcano is Kilauea on Hawaii, which since the mid 1980's has erupted an average of 3.5 times per year. (An eruption denotes vigorous activity either from a new volcanic vent or from an established volcanic vent after a slowdown). What is the probability that over the next 18 months, Kilauea will have more than 2 eruptions? What is the expected number of eruptions during the next 6 months?.
