In the daily practice lrdi set that has been given today (13/8-venn diagram), it is possible to find the variables 'c', 'd' and 'i' and 'g' using the 4th point right?It had no effect on answering the questions since 'h' and 'j' cannot be found and questions were based on that. I dont know if im wrong or if not,why havent they mentioned it in the solution?
