Solution: 11/26

Answer: DATE

First figure out what letters are on each dice. In addition, notice that some dice produce a letter more often than others.

d1 = ["D","B","N","Z","M","Y"]
d2 = ["A","H","K","P","L","C"]
d3 = ["T","V","I","S","G","R"]
d4 = ["E","U","X","F","O","W"]

Taking the most frequent letter per dice, in order of dice that most often produces a letter, gives the answer DATE.

Author’s Notes

I played a bunch of Machi Koro 2 that day. I was going to write a dice + data puzzle but after a bunch of coding, I ran out of time and settled on the current version with its fairly sus extraction. I actually wrote code and rolled several times until the most likely letter per dice was actually the most frequent letter per dice.

The dice are weighted [d1, d2, d3, d4] have a [0.7, 0.6, 0.5, 0.4] probability of producing a letter and the individual letters on each die were weighted [0.25, 0.15, 0.15, 0.15, 0.15, 0.15].
