Astronomers treat the number of stars in a given volume of space as a Poisson random variable. The density in the Milky Way Galaxy in the vicinity of our solar system is 1 star per 16 cubic light years. How many cubic light years of space must be studied so that the probability of 1 or more stars exceeds 0.98?  Round your answer to the nearest integer.
