Casino X advertises that it has the “loosest” one-dollar slot machines in town, which means that the statistical odds of winning money playing a one-dollar slot machine are greater at Casino X than at any other casino. Meanwhile, Casino Y claims to have the loosest five-dollar slot machines in town. In any event, the statistical odds are always against any slotmachine player. Elaine has five dollars to spend on gambling and has decided to play a five-dollar slot machine at Casino Y.
Assuming Elaine hopes to win money, which of the following, if true, provides the strongest evidence that she made a good decision as to how to gamble her money?
(A) Casino Y’s total gambling revenues far exceed those of Casino X.
(B) At Casino Y, more gamblers win money playing slot machines than at any other casino game.
(C) One of the two casinos is providing accurate information about its slot machines, but the other casino is not.
(D) Each of the two casinos has both types of slot machines: one-dollar and five-dollar.
(E) Casino X and Casino Y are the only two casinos in town that claim to have the loosest slot machines of any type.
Choice (B) provides at least some evidence that the slot machines at Casino Y are “loose” and accordingly that Elaine’s chances of winning at one of those machines is relatively good.
