During the summer of 1983, the McDonald's Corporation ran a promotional game. With each purchase, a customer received a game card. Each game card had ten spaces hidden from view. In eight of these spaces, the names of eight different McDonald's products appeared. In one of the remaining two spaces, one of these eight product names appeared again. Thus, nine spaces contained only one possible pairing of product names. The remaining space contained something different; we'll call it an "X". To play, the game card spaces were revealed, 1 at a time, in any order. Play ended when either the pair was uncovered or the X appeared (a loss). Thus, every card could be a "winner". What was the probability of winning this game?
