That's actually probably my favorite single question: when I first took the survey I went 'universe: dunno, maybe 60%, Milky Way: eh, 30%.....wait a second aren't there more than 2 galaxies‽'

I was pretty sure there were about 100 billion galaxies so I just divided by that factor.

That assumes aliens arising in each galaxy is an independent event when conditioning on your uncertainty.
