1. The problem statement, all variables and given/known data The question is: Four cards are dealt from a well-shuffled pack of 52 cards. What is the probability that all four cards bear the same face value? 2. Relevant equations n/a 3. 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?
