The drop chance for each individual run stays the same. Repetition does not increase the drop chance as such. What it does increase is the probability to get what you want the more repetitons you do.

*But there is no guarantee for success even at 99.99% probability.*

This calculator gives you an indication of the number of tries you have to expect.

This calculator gives you an indication of the number of tries you have to expect.

The calculation of how many tries should give at least one positive result is done by using the chance to fail.

10% drop chance means a 90% probability (0.9) to fail. For 10 runs this means a probabilty 0.9^{10} to fail. This results in 0.35, meaning 35% chance of not succeeding in 10 runs. And this again means 65% chance of succeeding (at least once) in 10 runs.

10% drop chance means a 90% probability (0.9) to fail. For 10 runs this means a probabilty 0.9
