Counting and Probability: Conducting Simulations

Anna did not study for her Chemistry quiz. The quiz consists of $4$ true or false questions. In order to pass the quiz Anna must get three out of four questions correct. Anna decides to guess on each question. $\\$

A simulation is conducted to determine the probability of Anna passing the quiz. A normal coin is used in the simulation to determine if the question is answered correctly or incorrectly. Heads represents a correct answer, tails represents an incorrect answer. Since there are four questions, a coin is flipped four times per trial to represent the answer to each question. The table below shows the results of each trial.
