This question takes several minutes. It requires you to plot an AP curve manually.

What would be the Average Precision (AP) @ 10 of the following query results, assuming that all the expected elements were retrieved:

1. relevant
2. relevant
3. NOT relevant
4. NOT relevant

5. NOT relevant
6. relevant
7. NOT relevant
8. NOT relevant
9. NOT relevant
10. NOT relevant
11. NOT relevant
12. NOT relevant

You can compute an approximation of the AP using the upper envelope of the Precision Recall curve.

Please provide at least 2 significant digits ("0.XY" format).
