If the pick is completely random, the deck is a standard deck and there are no jokers or any other cards other than the standard 52, the probability is 1/4
you have a 1/13 chance of getting an ace in a pack of cards
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
4/13
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
The probability of drawing a heart from a fair deck is 1 in 4. If the card is replaced then the probability is again 1 in 4. The probability of drawing a card other than a heart is 3 in 4. Once again if the card is replaced then the probability remains 3 in 4
13/52 = 1/4
you have a 1/13 chance of getting an ace in a pack of cards
There are 52 cards in a deck with no jokers. There are 13 hearts in such a deck so the probability of drawing a heart is13/52

It is 1: a certainty. A complete pack of cards must have a seven.
A 1/13 Chance (Probability).
10/13

It is 1/4.
1/2 or 0.5.
