papua new guinea.
1 of my favorite colors!!!!!
It never accepts the answer then says I have it right, and to top it, marks it as France!
Given we're choosing 20 random countries here, the chance none of them share a border would be about 54%. So even with this very liberal and rough approach, we see that half the time bordering countries should show up.
However, now let's account for the 40 countries without borders, so we get 156 countries with borders. And now our % becomes (assuming 4 / 20 countries are borderless) 16.8%. So actually even with these liberal benefits (in your favour) we get that 1 in 6 times you play this quiz should have all borderless countries.
In reality, you'd probably be looking at more like 1 in 20 times given if you got Russia, China or France that immediately removes 10+ countries.
Overall: this quiz is truly random, and humans don't think true randomness is random at all.
