Answer:

P(red card, then 4 of spades)

= (26/52)(1/52) = (1/2)(1/52) = 1/104

Step-by-step explanation:

We start with 52 cards, 26 of which are red. So P(red card) = 26/52 = 1/2. Since this card is put back in the deck, we have the same 52 cards, 1 of which is the 4 of spades. So P(4 of spades) = 1/52, and it follows that P(red card, then 4 of spades) = (1/2)(1/52) = 1/104.
