Elisa took a quiz that had 20 multiple choice questions. Since each question had four answer choices, she decided to roll a four-sided die to determine her answer. If the die landed on 1, Elisa chose A, if the die landed on 2, she chose B, and so on. Elisa's answers are shown in the chart below. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 D A A C B C A D A B B A B A C A D B A D If Elisa got all of the D answers wrong and she got all of the A, B, and C answers correct, what is the probability that a randomly selected question from the quiz would have a correct answer?
