Hi there, nice work. I have read the Gygax75 challenge, so I'm a fan of your work.
I have two suggestions:
- Your "dice chain" section includes the expected values of each die, but, expected values are useful in all games of dice. It's generally useful to know that a d6 can be expected to produce a value of 3.5 (even though it never will... but if we ran an infinitely long Monte Carlo simulation you would see it converge to that value). So, if it was my zine, I would put that in a section called "Expected Values".
- Of particular interest would be expected values of rolling dX with advantage and disadvantage. Eg: when rolling 2d20 to obtain a d20 with disadvantage, your expected value from 10.5 to ~ 7.2, and it's the opposite case with advantage. There's some interesting maths about it on this page: https://rpg.stackexchange.com/questions/14690/how-does-rolling-two-d20-and-takin...
Also, good information, might be to make a reference to the gambler's fallacy. People sometimes think that if you flip a fair coin and it comes up heads 20 times, then it must be more likely to be tails next time. No, the odds of a fair coin will always be 1:1. The same applies to dice. If the dice hate you so far then unfortunately that doesn't mean your luck will improve.
I could spam you with probability tidbits but there's only so much time haha.
