There are a total of 80 questions, so the probability of selecting a question number greater than 67 can be calculated by dividing the number of questions greater than 67 by the total number of questions:
Number of questions greater than 67 = 80 - 67 = 13
Total number of questions = 80
Probability = Number of questions greater than 67 / Total number of questions
Probability = 13 / 80
Probability = 0.1625
Therefore, the probability that the question number is greater than 67 is 0.1625 or 16.25%.
