The Aleutian Islands of Alaska are a very volcanically active archipelago, with an average of 1.3 eruption events per year. Eruptions can disrupt flight paths between northern North America and eastern Asia, entailing financial and logistical challenges for the airline industry and for air traffic controllers. If we assume that the variance of annual eruptions in the Aleutians is also 1.3 and we wish to calculate the probability that there will be k=0 eruptions in 2021, we should use the - probability model.
