Answer:
1/104
Step-by-step explanation:
Probability that the first card is a club = 1/4. (There are 13 club cards in the deck, and 13/52 = 1/4).
Probability that the second card is a 3 = 1/13. (There are four 3 cards in the deck, and 4/52 = 1/13).
Probability that the third card is red = 1/2. (There are 26 red cards in the deck, and 26/52 = 1/2).
Probability that the first card is a club, the second card is a 3, and the third card is red = 1/4 * 1/13 * 1/2
= 1/104
