Question 195 on page. 249, is asks how many routes from x to y can be taken that have the minimum length, How did you go about counting the routes at first I thought the question was a combination or permutation, but reading the explanation am I just suppose to draw the picture and start crossing off routes seems the wrong way to go about it.

Valdmire , kind request:

Can you please make sure that 'atleast' you change a subject of your post? It appeared to me as if by mistake you have posted the same post twice. Atleast you can append the Question number with O.G.

Back to Question : can you please post the question here?

Thanks mate !
