Question

20 students plays football and 16 students plays hockey.It is found that 10 students plays both game.Find the number of students playing at least one game​

Answer 1

36 because in total there are 46, 20 playing football, 16 playing hockey and 10 who plays both so if you add 20+16+10 you get 46, but then you take away the 10 who play both to get an answer or 36 students
