Liber de ludo aleae

Liber de ludo aleae is a seminal work by Girolamo Cardano that introduces the concept of probability as the ratio of favorable to possible cases.

It discusses various aspects of gambling, including the law of large numbers and the psychology of players.

Although it was written in the mid-1500s, it was not published until 1663.

The book is significant for its early mathematical treatment of probability but has been criticized for its lack of clarity and contradictory methods.
