Astronomers treat the number of stars in a given volume of space as a Poisson random variable.

Question:

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 one star per 16 cubic light-years.

(a) What is the probability of two or more stars in 16 cubic light-years?

(b) How many cubic light-years of space must be studied so that the probability of one or more stars exceeds 0.95?
