InterCasino, an online gambling web site at www.intercasino. com, recently offered a free flight to New York as a promotional offer to new customers. From Australia, the value of the flight was about $2,000. To qualify, players had to complete their wagering requirements for one of the online games. Assuming the player was happy with the terms and conditions of the offer, two obvious questions are: Is the offer worthwhile? Which is the best game to play? To answer these questions, we need probability theory, details concerning the games, and clear criteria on which to base our answers.
