Relative-frequency based definition of probability( von Mises, 1919)

If an experiment is repeated times under similar conditions and the event occurs in times, then                                                       

Example 8 Suppose a die is rolled 500 times. The following table shows the frequency each face.



                                           
We see that the relative frequencies are close to . How do we ascertain that these relative frequencies will approach to as we repeat the experiments infinite no of times?

Discussion This definition is also inadequate from the theoretical point of view.

    • We cannot repeat an experiment infinite number of times.
    • How do we ascertain that the above ratio will converge for all possible sequences of outcomes of the experiment?
