Carl Sagan explaining the Drake equation:

N = R*•fp•ne•fl•fi•fc•L

"In 1961, Carl’s close friend, fellow astronomer Frank Drake, created an equation for calculating the number of intelligent civilizations in the galaxy."

The Drake equation is:

N = R*•fp•ne•fl•fi•fc•L
where:
N = number of civilizations in our galaxy with which communication might be possible (i.e. which are on our current past light cone);
&
R∗ = average rate of star formation in our galaxy
fp = fraction of those stars that have planets
ne = average number of planets that can potentially support life per star that has planets
fl = fraction of planets that could support life that actually develop life at some point
fi = fraction of planets with life that actually go on to develop intelligent life (civilizations)
fc = fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = length of time for which such civilizations release detectable signals into space
