The game of dice has been popular for thousands of years, so it’s obvious that eventually it started to inspire people to research the probability and statistical correlations. There is no proof available to modern historians regarding anything happening in this area before the Middle Ages in Europe. Willbord the Pious in the year 960 and Richard de Furnival in the 13th century analyzed the game in different ways, but it was not probability science.
The person considered to have conducted mathematical analysis of dice for the first time was Jerolamo Cardano, an Italian scientist, in 1526. Galileus, Pascal and Christiaan Huygens with his manuscript called “De Ratiociniis in Ludo Aleae” all have improved on this theory and developed the science of probability much further.
People used to belive, and some of them still do, that events are controlled by God or other supernatural factors. Mathematical theories say that some events are casual in nature and happen without a reason, and that’s where the concept of probability and the interrelation between accidents comes from.
Equally probable events have equal odds to happen at all times, in gambling too. In random games all events are completely independent from previous events. A large number of events is necessary to see the expected correlations. Separate events cannot be predicted. But in the end the probability of winning or losing doesn’t have that much to do with having fun, does it?
