Thanks for posting, it was well done. I was looking into the percentage of stars that are in binary or triple systems, and came up with a few answers. This one sums it up well:

The Question
(Submitted April 02, 1998)

What percentage of the stars are binary systems?

The Answer
Somebody once said that "2 out of every 3 stars are in a binary". Seriously, the fraction is very high, but it's difficult to be precise, because it's difficult to prove that a certain star is definitely single. Of the stars nearest to the Sun, about half are known to be in multiple systems.
