If two cards are dealt, find the probability that they are a pair.
============
The 1st card is random.
For the 2nd card to match, there are 3 of them in the remaining 51 cards.
3/51 = 1/17
===========================
===========================
This is silly. Like someone doesn't know what a pair is.

Once you pick your card, there are 3 possible matches remaining in the deck of (now) 51 cards. So the probability of choosing the match is,
P=3%2F51=1%2F17
