grinding process certainty


Probability Theory

Thus, the outcomes of a random experiment cannot be predicted with certainty. How-ever, if random experiments are repeated sufficiently frequently under identical con-ditions, stochastic or statistical regularities can be found. Examples of random exper-iments are: 1) Counting the number of vehicles arriving at a filling station a day.
