I am writing a paragraph about a mathematical condition which is "always false except by chance". This chance is very very low, almost zero, meaning the case for the condition being true will, in practical terms, never happen. Yet, strictly speaking, it could.
Is there a one-word quantifier which can express this condition ("always, except by chance")?
"The condition is always false" is not appropriate, because always is too strong (chance still exist for condition to be true)
"The condition is mostly false" is not appropriate, because it speaks of many cases where it holds. The case will almost never happen.
I have been looking at other quantifiers or adverbs online, but cannot come across one.
