The distribution of warfare over time was studied by a researcher. He deduces from the data that the number of wars that start in a given year follows a approximately Poisson distribution with a parameter λ=2.8. Find the probability that the following number of wars will occur if a calendar year is chosen at random: Zero At most two More than 7 At most 10 Less than 6
