The odds are 1:13 - since there are 52 cards, and 4 queens in each pack.
A standard deck of card consists of 52 playing cards (excluding the jokers). Half of the deck is black and half of the deck is red. Therefore, there are a total of 26 red cards.
There are 52 cards in a deck, and 4 suits of 13 cards each.So the probability is 1/13 = 0.077
In a standard 52 card deck: 4 queens / 52 cards = about 7.69 %In a deck with the jokers: 4 queens / 54 cards = about 7.41 %In a Pinochle deck: 8 queens / 48 cards = about 16.67 %In a standard modern Tarot deck: 4 queens / 78 cards = about 5.13 %etc.
There are 52 cards in a pack of playing cards (excluding jokers). The chance of drawing at random a black card from a full pack of cards is 1/2, or 0.5. There are now 51 cards in the pack, two of which are red kings. The probability of drawing a red king from this pack is 2/51. 0.5 x 2/51 = 0.01960784 So, the probability is approximately 0.0196, or 1.96%.
