The probability that the student chosen at random is not a male that had a A grade is 0.85.
<h3>What is the probability?</h3>
Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability = (number of students - males who had a A grade) / total number of students
(59 - 9) / 59 = 50 / 59 = 0.85
