Astronomers estimate that as many as 100 billion stars in the Milky Way galaxy may be encircled by planets. Let p denote the probability that any such solar system contains intelligent life.

How small can p be and still give a 50-50 chance that there is intelligent life in at least one other solar system in our galaxy? (Hint: Use the probability distribution designed to handle problems where the probability is small and n is large.)
