**1 bit = IDs 1/2 of all results**
When you have a sample population to make a random selection from, 1 bit of information is enough to cut that population in half.

2 bits cuts your possibilities in half _twice_.
3 bits cuts your possibilities in half 3 times.
The general formula for bits of information is:
$
(\frac{1}{2})^I=p
$
Where “I” is information, measured in bits, and “p” is the probability of a random selection being identifiable.
