On one random draw, the probability is 2/13.
3 out of 13
1/52
It is 3/13.
In a normal deck of cards, it is 1.
12/52nd
13/52
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.

3 out of 13
It is 3/13.
In a normal deck of cards, it is 1.
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.
Prob = 0.
12/52nd
The probability of pick a red ace out of a standard deck of cards would be 1/26 because there are two read aces, the ace of diamonds and the ace of hearts.
There are 13 of each suit in a standard deck of cards. Assuming there are no jokers, the probability of picking either a club or a diamond is (13+13)/52 or 0.5. There are also four aces in a standard deck. However, we've already accounted for two of them (the ace of clubs and the ace of diamonds), so we're only adding two additional possibilities. The probability of choosing an ace, a club, or a diamond from a standard deck is therefore 28/52 (you can figure the decimal value yourself).
