Lotteries bank on their reliability. You need to stick to the promises about prizes that you make to your customers. This means that your marketing activities can only include statements that will stand up to solid mathematical inspection. That isn’t all that easy, however. It calls for sound statistics, a great deal of technical understanding and precise knowledge of the products. Within lottery companies, the gaming operations departments are typically responsible for providing all of the above. As is usually the case with complex, security-relevant topics, though, securing external safeguarding from a second, reliable source is an ideal way of excluding sources of error.
