Er, you've switched argument. It's the probability of carrying
*them* (not *it*) out correctly which is important, and that
probability changes.
If you carry out an operation with a 99% success rate 23 times, the
likelihood of success overall drops to under 80%. Do it 69 times and
you're more likely to fail, than succeed overall.

That just makes it easier to accidentally wipe an important stick
(by shifting the point at which you take extra care).
