We simply divide the number of jars in each weight category by 100 to give the probabilities.
| Weight X | Number of Jars |
Probability P(a ≤ X < b) |
|---|---|---|
| 0.900 - 0.925 | 1 | 0.01 |
| 0.925 - 0.950 | 7 | 0.07 |
| 0.950 - 0.975 | 25 | 0.25 |
| 0.975 - 1.000 | 32 | 0.32 |
| 1.000 - 1.025 | 30 | 0.30 |
| 1.025 - 1.050 | 5 | 0.05 |
| Total | 100 | 1.00 |
