# Coincidence

Coincidence can be expressed as a raw probability ${\displaystyle p:[0,1]}$ or as an adjusted quantity, which is measured in Stans (${\displaystyle \varsigma }$):
${\displaystyle C=\tan \left({\frac {\pi }{2}}(1-p)\right)}$
The probability of rolling a number between 1 and 6 inclusive is ${\displaystyle p=1}$ or ${\displaystyle 0\,\varsigma }$ (0 Stans). The probability of 10 people rolling the same number is ${\displaystyle p=(1/6)^{10}}$ or ${\displaystyle 38.5M\varsigma }$ (38.5 million Stans).
