What is a D3?
A D3 is a three-sided die. It has 3 faces numbered 1 to 3, and on a fair die each one is equally likely, so any single face comes up 33.33% of the time. You will usually see it used for small damage rolls and minor random outcomes.

D3 odds
Every face on a D3 has the same 33.33% chance. Rolling the die more than once does not change that. Each roll is independent, so a run of low numbers tells you nothing about what comes next.
Across many rolls the average settles near 2, which is the number to use when you are comparing this die against another.
