WebNov 19, 2015 · The division rule states that "There are n/d ways to do a task if it can be done using a procedure that can be carried out in n ways, and for every way w, exactly d of the n ways correspond to way w" I really can't understand this definition. Is there a easy way to explain this rule, not using math terms?
