A common feature of all lotteries is a pool or collection of tickets and their counterfoils that are used to determine the winners. Normally, this pool is thoroughly mixed by shaking or tossing them, and a random number or symbol is chosen for each prize. A percentage of this pool is deducted for organizational and promotion costs, while the remaining amount is distributed to the winners. The prizes can range from small amounts to very large ones.
