This is undefined. Without more information you don’t know the exact number of people.

Riddle me this, why didn’t you do a better riddle?

Person 1: "I need chairs for two fathers and two sons to sit"

Person 2: 'Okay, I have no idea how many chairs to grab, not enough information' - nobody ever

(Person 2 has no ability to contribute to anything of economic value.)

[Der_Einzige]

Anyone who talks like person 1 contributes negative economic value.

No sounds like a normal person lol. Just ask an LLM why I'm right and you're wrong. You're welcome.

No, but you can establish limits, like the total set of possible solutions.
