Coincidence

Coincidence is the effect of quantifying the degree to which two events are said to be uncorrelated in causality. Many real effects are often dismissed as just a coincidence, when really there is a possibly hidden or unrealized link between the two.

Coincidence can be expressed as a raw probability $p:[0,1]$ or as an adjusted quantity, which is measured in Stans ($\varsigma$):

$C=\tan \left({\frac {\pi }{2}}(1-p)\right)$

The probability of rolling a number between 1 and 6 inclusive is $p=1$ or $0\,\varsigma$ (0 Stans). The probability of 10 people rolling the same number is $p=(1/6)^{10}$ or $38.5M\varsigma$ (38.5 million Stans).
