Sorry if the question is confusing. Question is in the description.Posted by: Mathgeekjoe
So lets say I have a population of shapes, 70% are quadrilateral. 30% are triangles. Now lets say there are shapes that are regular polygons. 60% of regular polygons are squares. 40% of regular polygons are equilateral triangles. Now here comes the question. Which type of shape is more likely to be a regular polygon?
Since it appears the question focuses on how we interpret that last question you posted, I'll guess you meant for use to compare the probability of regular GIVEN quadrilateral and the probability of regular GIVEN triangle. For the proof of why triangle's probability is higher: http://pastebin.com/026YxurZ
