A survey of 120 high school students recorded whether each student plays on a sports team and whether each student attends after-school music lessons.
| Attends music lessons | Does not attend music lessons | |
|---|---|---|
| Plays sports | 30 | 50 |
| Does not play sports | 20 | 20 |
If one of the students who plays sports is selected at random, what is the probability that this student also attends music lessons?
