If there are 4 ninth graders total, and 3 of them don’t like action, the probability of a randomly selected ninth grader not preferring action is 3/4.
If there are more than 4 ninth graders total - the survey suggests that approximately 3/4 ninth graders do not prefer action. We can then approximate the probability that a randomly selected ninth grader does not prefer action as 3/4.
