If you select 20 random countries from the world map like in
this quiz, what is the chance you get each amount of countries from each continent?
South America and the Caribbean have the same number of countries. The line for South America is therefore hidden behind the line of the Caribbean.
Some percentages may have been rounded to zero since they are too small.
