The Attempt at a Solution
My guess is that first of all, I pick a card out of random, 1/52. Then after that, I have 12 chances of picking the same face value out of 51 cards, so that is 12/52. Then I continue this for the other cards, so I get:
1/52 + 12/51 + 11/50 + 10/49 = 0.68
The thing is, I can't help but think that's a bit high. Have I missed something glaringly obvious, or have I done it right?
