Question

Two cards are selected at random without replacement from a well-shuffled deck of 52 playing cards. Find the probability of the given event

A pair is drawn

Answer 1

If two cards make a pair, I believe the answer is 1/104

Not sure tho..

Answer 2

consider the deck either as 4 suits of 13, or as 13 suits of 4.

P(same suit) = 1 * 12/51
P(~pair) = 1-P(pair) = 1 - 1 * 3/51
