Final answer:
Without specific performance data, we can't calculate the exact percentage of questions Elizabeth correctly answered. For random guesses on a multiple choice or true-false quiz, the probability of a single correct answer is 33.33% or 50%, depending on the number of choices. Guessing more than 75% correct across the entire quiz would require complex probability calculations.
Step-by-step explanation:
To determine what percent of the questions Elizabeth correctly answered, we need additional specific information about her performance. Without that, we cannot calculate the exact percentage of questions she got right. However, if we consider the scenario where a student randomly guesses the answers in a true-false quiz, we can discuss probabilities broadly.
When guessing on a multiple choice exam or true-false quiz, if each question has only two or three possible choices, the probability of guessing any one question correctly is simply 1 divided by the number of choices. For example, if there are three choices, the probability of guessing correctly is approximately 33.33%. If there are only true or false answers, the probability of guessing correctly is 50%. However, guessing more than 75% correct on the entire quiz involves more complex calculations, utilizing combinatorics or probability distributions, which go beyond the scope of this simple explanation.
