Plugging in my numbers, I get 0..3, so the probability is that we don't
exist.
There are two factors that SETI never seems to look at.
1. What percentage of intelligent species ares paranoid ("We don't want to
attract their attention, they are probably dangerous")?
2. Technology (already we are moving our communications into spread-spectrum
technology which would be virtually undetectable except as a slight rise in
background noise, leaving maybe a 200 year window of indiscriminate
electromagnetic radiation).
Factoring in those concepts is how the equation gave me a 0.3% chance of
communication with ETI.
