If someone has a success rate of 90%, they fail twice as often as someone who has a success rate of 95% (10 times per 100 vs 5 times per 100) If someone has a success rate of 98% they fail twice as often as someone who has a success rate of 99% (2 times per 100 vs 1). Why is this the same?

Question

If someone has a success rate of 90%, they fail twice as often as someone who has a success rate of 95% (10 times per 100 vs 5 times per 100) If someone has a success rate of 98% they fail twice as often as someone who has a success rate of 99% (2 times per 100 vs 1). Why is this the same?

Answer 1

That’s not actually the case if you’re looking at present tense as its just a probability. If this is past tense (had a success rate of…) then the times that they failed is doubled. (1 out of 20 compared to 2 out of every 20, and 1 out of 100 to 2 out of every 100 attempts)
