Probability Unit
Gerolamo Cardano lived in the 16th Century and is known as the “father of Probability”.  He lived in Italy and was a renaissance mathematician.   He made many contributions to the field of Algebra and is credited with introducing binomial coefficients and the binomial theorem.

He was very smart, but he was considered strange and weird by many people and he didn’t have very many friends.  He was always short of cash, but he was an accomplished gambler and chess player, and he made enough money doing that to support himself.

Gerolamo Cardano (1501 - 1576)
He discovered many of the properites of probability and even wrote a book on probability called “Liber de ludo aleae”, but the book was not published until a hundred years after he died.  In the years following his death, mathematicians began to understand more about the theory of probability, and they recognized how much Cardano had actually contributed to the field.  Thus, he earned the title of “Father of Probability”
