A statistics student takes a pop quis that consists of three true false questions. Let's consider the experiment to be the answering of three questions where each can be either answered correctly or incorrectly. Let "C" represent the answering of any given question correctly, and "1" as answering the question incorrectly. Assume that the student has a 50% of correctly answering each question. What is the probability that the student gets all three questions wrong?
