Since you have already drawn a card which is an Ace then there will be remaining 3 aces in 51 cards. So probability of second card being an Ace is 3/51.
What is the probability that two cards drawn at random from a deck of playing cards will both be aces?
1/221
WITHOUT REPLACEMENT: If you draw two cards from the deck without replacement, what is the probability that they will both be aces? P(AA) = (4/52)(3/51) = 1/221.
When 2 cards are drawn without replacement What is the probability of getting exactly 1 heart?
The number of ways to select one heart out of the 13 hearts in a deck is . The number of ways to select 2 cards out of 52 cards in a deck without replacement is . Therefore, the probability of getting one heart and one spade after selecting two cards without replacement is which is about 0.1275.
What is the probability that the second card selected is an ace?
The probability that the first card is an ace is 452=113 . The probability that the second card is an ace is 452=113 . Therefore, the probability that both cards are aces is 113⋅113=1169 .
What is the probability of getting a pair by drawing 2 cards in a 52 card deck?
The “first” card doesn’t matter, as only the second card has to have the same rank. After removing one card, there are 51 cards left in the deck. 3 of them have the same rank as the card that was removed. Hence, the probability of getting dealt a pair is 3/51 = 1/17.
