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.
(a) What is the probability of 3 or more stars in 16 cubic light years?
(b) How many cubic light years of space must be studied so that the probability of 1 or more stars exceeds 0.93?
(a) The probability is [Round your answer to three decimal places (e.g. 98.765).]
(b) cubic light years of space. [Round your answer to the nearest integer.]
