Probability of Scoring Above 90

A class of 30 students took a mathematics test, and their scores are shown below:

65, 70, 72, 75, 75, 78, 80, 82, 82, 85, 85, 85, 88, 90, 92, 93, 94, 94, 95, 96, 96, 97, 98, 98, 99, 99, 99, 100, 100, 100

Determine the probability that a randomly selected student from this class scored more than 90. Express your answer as a fraction in simplest form.
