Lottery
A lottery is a procedure for distributing something (usually money or prizes) among a group of people by chance. Such games have been used in ancient times to give away property and slaves; and they are still used by some governments for raising funds for public projects.
The basic elements of a lottery are usually quite simple: there must be some means of recording the identities of the bettors, the amounts staked by each, and the number(s) or other symbols on which the money is bet. The bettor may write his name on a ticket that is deposited with the lottery organization for subsequent shuffling and possible selection in the drawing.
Another element of a lottery is the existence of a mechanism for collecting and pooling all the money placed as stakes. This is usually accomplished by a hierarchy of sales agents who pass money paid for the tickets up through the organization until it is “banked.”
While lottery revenue is an important source of government income, the way in which it is distributed is not always transparent to consumers. States often have to pay out a significant portion of their ticket sales in prize money, which reduces the percentage available for state revenue or use on things like education.
