Kakashi told the group that there is 66 per cent failure rate, that means only 9 of the 27 academy graduates can pass. And it's in the hand of jonin who is instructing a group of 3, whether he/she want to pass his group or not. So what if all jonin want to pass their group, then how the failure rate would be maintained in that case?
How a Jonin ensured that they can pass their genins as there should be only 9 graduates?
Is that an absolute limit, or an observation? Does it actually mean that only nine can pass, or that (on average) of a class of 27, nine will pass?– MaryMar 31, 2022 at 0:09
The latter one, of a class of 27, nine will pass.– somanshuMar 31, 2022 at 19:30

The rate is a measurement, not a rule. If the 27 students had passed, they'd all become genin. The 66% rate is just the statistics considering the rate of graduation up to that point.
