3 out of 13
It is 3/13.
12/52nd
In a standard deck of 52 playing cards, there are 13 hearts. To find the probability of picking a heart card, you divide the number of heart cards by the total number of cards. Therefore, the probability is 13/52, which simplifies to 1/4 or 25%.
A standard deck of playing cards contains 52 cards, with 26 red cards (hearts and diamonds) and 26 black cards (clubs and spades). There are no green cards in a standard deck. Therefore, the probability of randomly picking a green card from a standard deck is 0%.
In a normal deck of cards, it is 1.
The probability of picking a diamond out of a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.

The probability of picking a 23 of hearts in a standard 52 card deck of cards is zero, because there is no 23 of hearts. If you meant to ask about the probability of picking a 2 or a 3 of hearts, then the probability is 2 in 52, or 1 in 26, or about 0.03846.
To determine the probability of picking 3 cards of one suit and 1 card of another in a standard 52 card deck, consider each card one at a time. The probability of picking a card in any suit is 52 in 52, or 1. Since there are now only 12 cards in the first suit, the probability of picking a card in the same suit is 12 in 51, or 4 in 17, or 0.2353. Since there are now only 11 cards in the first suit, the probability of picking a card in the same suit is 11 in 50, or 0.22. Since there are still 39 cards in the remaining three suits, the probability of picking a card in a suit different than the first is 39 in 49, or 0.7959. The probability of picking 3 cards of one suit and 1 card of another in a standard 52 card deck is, therefore, the product of the probabilities of each card, or (52 in 52) (12 in 51) (11 in 50) (39 in 49), or 267696 in 6497400, or 0.0412, or about 1 in 25.
The probability of picking one red card of a deck of 52 playing cards is 26 out of 52, or 1 out of 2.
The answer depends on how many cards are picked. It is 1 if you pick 49 cards without replacement. If only one card is picked at random, the probability is 1/13.
If it is an ordinary pack of playing cards then the probability is 0.5
In a normal deck of cards, it is 1.
