Quizplus · Accepted Answer

The total number of workers is 40 skilled + 30 unskilled = 70 workers. The number of college graduates is 25 skilled + 17 unskilled = 42. Therefore, the number of workers who are not college graduates is 70 - 42 = 28. The probability that a randomly selected employee is not a college graduate is 28 out of 70, which simplifies to $\frac{2}{5}$.
