i assume you are familiar with the Drake equation. Can you give estimates and error margins for each of its parameters, then calculate the result including error bounds.

The Dra ke equation is a tool used to estimate the number of extr ater rest rial civil izations in our galax y with which we might be able to communicate . The equation is as follows : \n \n N = R \ * f p \ * ne \ * fl \ * fi \ * f c \ * L \n \n Where : \n \n N = number of extr ater rest rial civil izations in our galax y with which we might be able to communicate \n \n R = rate of star formation in our galax y \n \n fp = fraction of stars with plan ets \n \n ne = average number of plan ets that can support life per star with plan ets \n \n fl = fraction of plan ets with life that become inhab ited \n \n fi = fraction of inhab ited plan ets that develop intellig ent life \n \n fc = fraction of intellig ent civil izations that develop detect able technology \n \n L = length of time for which such civil izations release detect able signals into space \n \n Est im ating the values for each of these parameters is a complex and on going process , and there is significant uncertainty associated with each estimate . Here are some possible estimates and error marg ins for each parameter : \n \n * R : 1 - 2 stars per year \n * f p : 0 . 5 - 1 . 0 ( dep ending on the definition of a planet ) \n * ne : 0 . 5 - 1 . 0 ( dep ending on the definition of a habit able planet ) \n * fl : 0 . 0 1 - 0 . 1 ( dep ending on the definition of life ) \n * fi : 0 . 0 1 - 0 . 1 ( dep ending on the definition of intellig ent life ) \n * f c : 0 . 0 1 - 0 . 1 ( dep ending on the definition of detect able technology ) \n * L : 1 0 0 - 1 0 0 0 years \n \n Ass uming that the values for each parameter are equally likely to be within their respective error marg ins , we can calculate the result of the Dra ke equation as follows : \n \n N = ( 1 - 2 ) \ * ( 0 . 5 - 1 . 0 ) \ * ( 0 . 5 - 1 . 0 ) \ * ( 0 . 0 1 - 0 . 1 ) \ * ( 0 . 0 1 - 0 . 1 ) \ * ( 0 . 0 1 - 0 . 1 ) \ * ( 1 0 0 - 1 0 0 0 ) \n N = 0 . 0 0 0 1 - 0 . 0 0 1 \n \n This means that there could be between 1 and 1 0 0 0 extr ater rest rial civil izations in our galax y with which we might be able to communicate . However , it ' s important to note that these estimates are highly uncertain and subject to revision as our understanding of the universe and the Dra ke equation parameters impro ves . </s>
