Expert Solution

There are 52 cards
2 cards are the red 7s (Diamond 7 and Heart 7)
P(picking a red 7 in the first draw) = 2/52 = 1/26

Since the first card is replaced in the deck
there are again
2 cards of red 7s in the deck

P(picking a red 7 in the second draw) = 2/52 = 1/26

P(picking both red 7s ) = 1/26 * 1/26
       = 0.0015
