Quizplus · Accepted Answer

The probability that a person's cholesterol will be higher after taking the drug is calculated by dividing the number of people whose cholesterol went higher by the total number of people tested. Here, 40 people had higher cholesterol out of 300 tested, so the probability is $ \frac{40}{300} = \frac{2}{15} $.
