How does the Lottery make sure its drawings are random?
The West Virginia Lottery goes to great lengths to ensure the randomness of its drawings and to eliminate any possibility of a breach of security that could jeopardize integrity. All equipment is stored in a locked area of our drawing studio. Further, a numbered and recorded seal secures each ball case. Each seal is checked and verified every night prior to drawings by the Lottery’s security officer, the event manager and the independent auditor. For each game, we have multiple sets of balls. The ball sets to be used are randomly selected prior to each drawing by the independent auditor. The auditor monitors all drawing activities to make absolutely certain that all procedures approved by the Director are followed. All drawing-related activities are recorded on both video and audiotape. Prior to every drawing, pretests are conducted and following every drawing posttests are conducted to ensure the random drawing of numbers – to ensure that no one digit is drawn more often than another.
The Rhode Island Lottery goes to great lengths to ensure the randomness of its drawings and to eliminate any possibility of a breach of security that could jeopardize integrity. All equipment used in the drawings is secured at the television drawing studio. For each game, multiple sets of balls are kept on hand and are chosen at random for the nightly drawings. Pretests are conducted prior to every drawing, and post tests are conducted following the drawings. This is done to ensure the randomness of the numbers that no one digit is drawn more often than another. Each set of balls is periodically measured and weighed down to 1/1000 of a gram. The tests are conducted by engineers from the University of Rhode Island, and monitored by Lottery security staff.
