Historical Note

The discipline of probability theory is suggested by some sources to be a creation shared between Pierre de Fermat and Blaise Pascal.

They developed the fundamental principles in a series of letters in the year $1654$.

The field was developed significantly by Jacob Bernoulli, the results of his research appearing in his posthumous Ars Conjectandi of $1713$.
