Menus   The local diner offers a meal combination consisting of an appetizer, a soup, a main course, and a dessert. There are four appetizers, five soups, three main courses, and four desserts. Your diet restricts you to choosing between a dessert and an appetizer. (You cannot have both.) Given this restriction, how many three-course meals are possible?   A computer byte consists of eight bits, each bit being either a 0 or a 1. Assume that characters are represented using a code that uses a byte for each character. Some written languages, such as Chinese and Japanese, use tens of thousands of different characters. If a language uses roughly 97,000 characters, a computer code for this language would have to use how many bytes per character?
