There are a pair of interesting tables in, of all places, GURPS Zombies on pages 113 and 114.

Page 113 has a quick approximation of success (for low target numbers) or failure (for high target numbers) rates as simple fractions, intended to simplify resistance rolls and self-control rolls for hordes.

Page 114 has a table for approximating a large number of low-success-rate rolls with one higher-success-rate roll, intended for horde perception checks.
