Isn't this a question of how many people you select?

Sure.

My point is that so is the percentage of males in any sortition cohort.

Therefore, a consistent female census of 10% or less in all sortition cohorts, would be as unlikely as a consistent male census of 10% or less in all sortition cohorts.

In other words, having one sortition cohort result in 10% males would not be suspicious. Having every sortition cohort result in 10% males would be suspicious in the extreme. So much so that we should start looking for whoever is "putting their finger on the scale" so to speak.
