How To Win The Lottery According To Math

2016-3-28 · Expressed in percentage, we get: P (white) = ( 45 / 50 ) x 100 = 90% chances of getting drawn. P (black) = (5 / 50) x 100 = 10% chances of getting drawn. In layman''s term, we can say that the white marbles will get picked 90x every 100 draws, and the black marbles will only get picked 10x every 100 draws.

A study of mine water inrushes by measurements of in situ ...

2015-8-28 · This paper presents underground measurements (e.g., mini-frac tests) for in situ stress, hydraulic fractures, strata failures and hydraulic conductivity enhancement induced by coal extraction to study mechanisms of coal mine water inrushes. Mining perturbs the original state of in situ stress and results in stress redistribution. This causes rock failures and creates a water …
