Three brands of coffee, X, Y, and Z, are to be ranked according to taste by a judge. Define the following events: A: Brand X is preferred to Y. B: Brand X is ranked best. C: Brand X is ranked second best. D: Brand X is ranked third best. If the judge actually has no taste preference and randomly assigns ranks to the brands, is event A independent of events B, C, and D?
