Default Pack of Cards Probability Problem of Gigantic Proportions?

From a well-shuffled pack of cards (whatever that means!), what is the probability of finding JUST two cards, of the same rank (any rank), next to each other?Or maybe I should have worded it as " what is the probability of finding AT LEAST two cards of the same rank next to each other?"Either way, I have no idea how to tackle this, but my suspect intuition tells me the probability is > 0.5 from my son's practical experience.Is this an impossible ask or are my probability skills waning?
