Drake Equation N = R *f p *n e *f l *f i *f c *L where N is the number of communicative civilizations, R = The rate of formation of suitable stars like our Sun f p = The fraction of those stars with planets n e = The number of Earth-like planets per planetary system f l = The fraction of those Earth-like planets where life actually develops f i = The fraction of life sites where intelligence develops f c = The fraction of communicative planets (those on which electromagnetic communications technology develops) L = The "lifetime" of communicating civilizations
