How many would actually be able to build anything if it was purely random? How many tries of 100 people batches until they've built something?

Not arguing, just questions that came into my mind.

Random people would have the most varied set of skills. A single person can have skills that are useless for surviving in the jungle, but if any of the 100 people has a good enough idea of what to do, the rest can help.

Even non-random groups like your coworkers or immediate neighbors can have unexpected skills that will make you feel dumb.
