At a school enrichment fair, each of 40 students enrolled in either a robotics workshop or a creative writing workshop. The table summarizes whether each student takes the school bus.
| Transportation | Robotics workshop | Creative writing workshop | Total |
|---|---|---|---|
| Takes the school bus | 18 | 6 | 24 |
| Does not take the school bus | 9 | 7 | 16 |
| Total | 27 | 13 | 40 |
A student is selected at random from among the students enrolled in the robotics workshop. What is the probability that the selected student takes the school bus?
