Question Eight a Prove or disprove the set of codewords {10,010,101} is uniquely decodable b Let X be a discrete random variable on an alphabet of size five. Suppose the distribution of X is P=(1/4,1/4,p3,p4,p5), where the last three probabilities are unknown. Find the values of (p3,p4,p5) such that H(X) is maximized
