A factory produces two types of items, Item A and Item B, on two different machines, Machine 1 and Machine 2. The table shows the number of items produced that were found to be defective.
| Defective | Not Defective | Total | |
|---|---|---|---|
| Machine 1 | 25 | 475 | 500 |
| Machine 2 | 15 | 385 | 400 |
| Total | 40 | 860 | 900 |
If an item is selected at random from the total production, what is the probability that the item was produced on Machine 1 and is defective?
