What do you mean by upper value?
To find range of probability we need max - min right? I meant max when I said upper value.
We have 10 percentile which I believe means 10% or lower. Even if a bar graph is given I think this is a point graph. So for this whole section probability is constant and we can get min value maybe?
But, how do we find the max probability? 99 percentile doesnt include the top 1% , right? So how do we say rural or urban probability range is greater than the other?
There is a possibility that I may be missing something very basic.
