Tests that sometimes fail
Your math is mostly correct, except that for 100 flaky tests your test run will only pass in 4.8% of cases.
That's why it's very important to retry individual tests, and not the entire test run.

Oops, you're right. I was moving too quick and misread .04755 (4.8%) as .4755 (48%).
