if you draw a tree to show the number of ways to roll two 3 side diced how many possibilities would there be
(3 possibilities for the first die) * (3 possibilities for the second die) = 9 possibilities
what does a 3 sided die look like?
Are the two die different from one another in some way - like one red and one blue.
Do the three sides all have something different on them?
All 2 questions are relevant. But, assuming everything is different then CPhill answer is good.
