To find out the probability of something like this, you just find the number of diamonds and divide it by the total number of cards. In this case, there are 13 diamonds in a deck, and 52 cards. Dividing 13 by 52 gives 0.25. This can then be converted into a percentage, making the probability 25% or into a fraction, making the probability 1/4

The probability of drawing a diamond is a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.
what are the odds in favor of drawing a diamond from an ordinary deck
The probability of drawing a diamond from a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.
number of cards in a deck =52 number of cards that are not diamond =39 Probability that the card drawn is not a diamond= 39/52 = 3/4
The probability of drawing a king is 4:52The probability of drawing a diamond is 13:52 (or 1:4)The probability of drawing a king (0.07692...) then replacing that king into the deck then drawing a diamond is 0.019230769.If you leave the king out, the probability will be slightly greater (4/52) * (13/51)Unless the king you left out of the deck was a king of diamonds, in which case, the probability would be (4/52) * (12/51)
