why do (most) dice have the same face placements? As in, why is the 6 usually opposite to the 1, likewise with the 3 and 4? Does this affect the “fairness” of a dice roll, making it a 1/6 chance every roll as opposed to a different value?

Answer 1

Each opposing face has 7 “pips” total – 6+1, 5+2, 4+3. This minimizes differences in mass per face pair such that each number statistically will appear approximately the same number of times. You’re looking for a even distribution of the 6 numbers over time.
