A survey was conducted among 80 high school students to determine their performance in Math and Science. The results are summarized in the table below.
| Passed Science | Failed Science | Total | |
|---|---|---|---|
| Passed Math | 40 | 10 | 50 |
| Failed Math | 20 | 10 | 30 |
| Total | 60 | 20 | 80 |
If a student is chosen randomly from those who passed Math, what is the probability that this student also passed Science?
