2. Consider the class LA of all regular languages that contain only words of a length that is a multiple of 4. over the fixed three-letter alphabet A={a,b,c}. (a) Is La countable? (b) Is the class Ma countable where Ma consists of all languages over A that are not in LA? (c) Is the class LA MA countable? For each question, you must give a precise argument substantiating your answer. 2.
