Thanks for the quick reply, so this means that everytime I can only make a combination of two right? Example I choose (1,1) at first, so for my second choice I can only choose from 2,3,4,4,5 right?

So the possible combination would be

(1,1) , (1,2) , (1,3) , (1,4) , (1,5) , (2,3) , (2,4), (2,5) , (3,4) ,(3,5) , (4,4) , (4,5) , (5,5)

I've left out similar figures like 1,1 and 1,2 / 2,1 as I think 1,2 and 2,1 are same things no?

That's the exact question which came in a previous years exam. So if the question is ambiguous like this then what is the best way to proceed?
