Can you PLEASE help me?  I`ve read your page on combinations & permutations & still can`t see which my problem is.

I need to know how many possible paths there are from origin (0,0) to (4,3) on a graph ONLY moving up and right (not left or down).

To me, the set is (r,r,r,r,u,u,u).  But is it combination (answer 35), permutation (answer 5040) or have I really confused myself & it`s something else all together???
