We can get a random number by throwing some dice. We can get a random answer to a yes/no question by tossing a coin. But beyond these trivial things, randomness is serious business. When a lottery winner is picked you want to make sure that the number picked is truly random. As the mathematician Robert Coveyou once said: "Random number generation is too important to be left to chance."
