| No. of students | 3 | 4 | 1 | 0 | 4 | 5 | 2 | 1 |
The table above shows the distribution of marks of students in a test. Find the probability of passing the test if the pass mark is 5?
| 3 |
| 5 |
| 2 |
| 5 |
| 7 |
| 20 |
| 1 |
| 5 |
Total number of students = 20
| Marks | No. of students |
| 5 | 0 |
| 6 | 4 |
| 7 | 5 |
| 8 | 2 |
| 9 | 1 |
| 12 |
Pr(passing) = \(\frac{12}{20}\)
= \(\frac{3}{5}\)
