45 out of 50 times, the presence of bubbles indicates activity and will result in a good beer.
However, you have to remember that after fermentation there is a lot of CO2 trapped in solution and if the fermenter is moved, some of that will come out and you will see bubbles. Additionally, the lack of bubbles can't be seen as lack of activity since there could be a small leak in the fermenter seal which is allowing the escaping CO2 to bypass the airlock. Gravity samples are the only true way to know.
