Drake Equation Formula - Science

Formula:

N = R * fp * ne * fl * fi * fc * L


Where,

N = Number of Communicative Civilizations
R = Rate of Formation of Suitable Stars (Stars Such as Our Sun)
fp = Fraction of those Stars with Planets. (Current evidence indicates that planetary systems may be common for stars like the Sun.)
ne = Number of Earth-like Worlds per Planetary System
fl = Fraction of those Earth-like Planets (where Life actually develops)
fi = Fraction of Life Sites (where intelligence develops)
fc = Fraction of Communicative Planets (those on which electromagnetic communications technology develops)
L = Lifetime of Communicating Civilizations
