For a 400 billion of Formation of Suitable Stars, the fraction of those Stars with Planets is 30%. The Number of Earth-like Worlds per Planetary System is 3 and the Fraction of those Earth-like Planets is 20%. The Fraction of Life Sites is 30%, fraction of Communicative Planets is 10% and the Lifetime of Communicating Civilizations is 10,000,000 years, then according to drake equation, the number of communicating civilizations is N = (400000000000 x (30/100) x 3 x (20/100) x (30/100) x (10/100) x 0.001) N = 400000000000 x 0.3 x 3 x 0.2 x 0.3 x 0.1 x 0.001 N = 2160000
