If the die is small enough for you to hold in one hand, and the symbol covers only side yet is large enough to easily read with typical human visual acuity, based on the laws of geometry it would be safe to assume that the die has fewer than about 100 sides, yeah.
I think this part of the analogy equates to our ability to observe the rest of the universe over billion-year time frames and its apparent lack of alien life forms.
The Doomsday argument is part observational, after all.
