A lottery is a procedure for distributing something (usually money or prizes) among a group of people in accordance with chance. The prize is determined by drawing numbers or symbols from a pool of tickets sold (sweepstakes) or other entries (lottery). A large number of small prizes are usually offered, the total value of which is often predetermined before the ticket sales start. Lotteries can also raise money for public usage. They are very popular, and in the immediate post-World War II period states were able to expand their social safety nets with less onerous taxes thanks to the popularity of lotteries.
