1. Yes If % of loan a zero % interest is more than probability is more.
2. Can not be inferred from only one tab. Some relevant information may be in other tabs.
3. No only one village is satisfying this condition and its % of loan a zero % interest is less than average of all villages so probability will also be less.

Have to agree with Raghaw's explanation above
For 1, There is a positive correlation between the interest rates and the percentage of zero interest loans, so knowing that mean interest rate is greater than 45%, eliminates data points where percentage of zero-interest loans are lower, and thereby increasing the probability that the loan is a zero interest loan.
Nothing can be deduced about 2 from the given tab.
3, No, that leaves just one data point on the graph, and thus the probability which has the least percentage, this would actually decrease the probability


What are the Official answers?
