In all the Year Zero system books, there is printed the 'Chance to Succeed' table. The first column is the number of Dice, the second column is the success percentage, and the third column the the pushed roll success percentage.
From my limited memories of my college statistics class, I understand how the second column is calculated for base success.
However, for the life of me I cannot figure out how the third column is being calculated.
Can someone enlighten me on the formula being used? I just cannot figure out how Free League are getting those numbers.
Thanks in advance.
(Example of table below.)
