(b) Tiffany obtained data about the gross domestic product (GDP) and the birth ratefor 170 countries. She classified each GDP and each birth rate as either "low","medium" or "high". There were 74 countries that had a medium GDP and 43countries that had a high GDP. Among the countries that have 58 low birth rate,there were 3 countries that have a low GDP and 20 countries that have a mediumGDP, whereas among the countries that have high birth rate, there were 45countries that have a low GDP, 12 countries have a medium GDP and no countryhas a high GDP.i. Construct a contingency table to represent the information above.One of these countries is chosen at random. Find the probability thatThe country chosen has a low GDP or a medium birth rate.ii.iii.The country chosen has a low birth rate, given that it does not have a mediumGDP.iv. States with a reason whether or not the events 'the country chosen has amedium GDP' and 'the country chosen has a medium birth rate' areindependent.
