But if the person says, "there is one n", then the permutation {n,n} is one of 9 (out of 11) cases when you'll be right, i.e. the double is included.

But your strategy should also include you and your partner agreeing always to call the higher [or lower] number.
Then I make make the probability of being right equal to
(5/6)(4/5) + (1/6)(6/6) = 5/6
Do you agree?
