If you want your answer in an equation it should be this C=2n but you have then to complete solving it because you have more information than you gave. Good luck!
They aren't independent since the probability uses all the cards in the deck
So at the first deal we have the chance of 26/52 of getting a red card, at the second deal we have the chance of a 25/51 of getting another red card, so they aren't independent
