SAT Mathematics Practice Test 2

According to the table, there are $18+7=25$ graduates who passed the bar exam, and 7 of them did not take the review course. Therefore, if one of the surveyed graduates who passed the bar exam is chosen at random, the probability that the person chosen did not take the review course is $\frac{7}{25}$
Choices A, C, and D are incorrect. Each of these choices represents a different probability from the conditional probability that the question asks for.Choice A represents the following probability. If one of the surveyed graduates who passed the bar exam is chosen at random, the probability that the person chosen did take the review course is $\frac{18}{25}$ Choice C represents the following probability. If one of the surveyed graduates is chosen at random,the probability that the person chosen passed the bar exam is $\frac{25}{100}$ Choice D represents the following probability. If one of the surveyed graduates is chosen at random, the probability that the person chosen passed the exam and took the review course is $\frac{7}{200}$
