Answers two cards are drawn without replacement from a well-shuffled deck of 52 playing cards. what is the probability that the first card drawn is a diamond and the second card drawn is not a diamond?

There are 13 diamonds so the probability of drawing a diamond in 13/52 or 1/4.
There are 51 cards left and 12 diamonds so (51-12)/51 = 39/51
1/4 * 39/51 = 39/104 = 13/68
Your final answer should be 13/68. Hope this helps!
