Statistics are not really relevent here.   I dont think we can make any
good guesses on why it worked, because the slop in the these kind of
experiments tends to be relatively huge (10 fold).   Your self ligation
control can merely suggest that your self ligations or not cut plasmid
low enough so as not to interfere with selection of colonies with

This kind of result is not that unusual.   15 out of 24 looks damn good
to me.
