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 not drawn.

Answer 1

since there is no restriction on the first card, p(pair) = p(2nd card is same value as 1st card)

p(pair) = 1 * 3/51 = 1/17

p(no pair) = 16/17
