Jamal didn't study for the quiz in World History class, so he decided to guess. (This is not a good test-taking strategy, by the way.) The quiz consists of five multiple-choice questions, each with four possible answers. What are Jamal's chances of guessing the correct answer on all five questions? 1/72 1/144 1/256 1/1024
