If the selection is random, the probability is 16/52 = 4/13.
If you randomly pick a card from a standard deck of cards, that probability will be 1/4, since 1/4 of the cards are heart.
There are only 4 suits in an ordinary deck of playing cards. The probability of drawing a heart is 1 in 4, or 0.25.
The probability of drawing a heart in a standard deck of 52 cards is 13 in 52 or 1 in 4.
Number of cards in a deck = 52 Number of cards that are heart = 13 Therefore number of cards that are not heart = 52-13 = 39 Probability of not drawing a heart = 39/52 or 3/4
The probability, if you draw 40 cards, without replacement, is 1. That is, it is a certainty. The probability on a single random draw is 1/4.

If five cards are drawn from a deck of cards without replacement, what is the probability that at least one of the cards is a heart?
number of cards in a deck =52 number of cards that are heart =13 number of cards that are diamond =13 Probability that the card drawn is a heart or a diamond=13/52 +13/52 =26/52 or 1/2
A card is drawn from a standard deck of playing cards. what is the probability that a spade and a heart is selected?
Number of cards in a deck = 52 Number of cards that are spade = 13 Number of cards that are heart = 13 Probability that the card drawn is a spade and heart = 13/52 + 13/52 = 26/52 or 1/2
13/52
Probability of drawing a heart: 1/4 Probability of drawing a club: 1/4 Probability of drawing a heart or a club: 1/4 + 1/4 = 2/4 = 1/2
If the selection is random, the probability is 16/52 = 4/13.
If you randomly pick a card from a standard deck of cards, that probability will be 1/4, since 1/4 of the cards are heart.
