Gambling has been a popular activity since ancient times. The precise origins are unclear, but there is evidence of gambling from the time of the Greeks and Romans, and it was a common feature of medieval Europe. Modern casinos are generally based on the idea of maximizing profit and limiting losses by using sophisticated computer technology and statistical analysis.

The games of chance available at casinos vary widely, but the house edge is the one thing that is constant. This is the average profit that the casino expects to make from each game, and it is designed so that it will not lose money. In order to maintain this advantage, casinos must hire mathematically trained individuals called gaming mathematicians or gaming analysts. These professionals are charged with calculating the house edge and variance for each game in the casino.
