Waylon Rivera · Answer 1

52 total cards ... 13 total diamonds in the deck

P (1st card picked being a diamond) = 13/52

replacing the card, so the sample space remains the same

P (2nd card being a diamond) = 13/52

P (both) = 13/52 * 13/52 = 169/2704 = 1/16 <==

Yeller · Answer 2

Any suit is a quarter of the deck, or 13 cards out of 52, so with replacement the probability of picking two straight of any suit is the same.

P (DD) = (1/4) (1/4)

P (DD) = 1/16
