26:52 = 1:2
There are 2 red suits and 2 black suits. Therefore the probability of drawing a red card is 1/2. Or 50% chance.
Half the cards in a standard pack are black. Therefore the probability of drawing a black card is 1/2. Half the sides of a coin are "heads" so again the probability is 1/2. Therefore the probability you will both draw a black card and flip heads = 1/2 * 1/2 = 1/4.
Assuming there are no Joker cards the chance is one in twenty six. There are fifty two cards in a pack and only two of them are black kings.
Since 1/2 of the cards are red, the probability of drawing a red card is 1/2 or 0.5.
The probability of drawing three black cards from a standard pack depends on:whether the cards are drawn at random,whether or not the drawn cards are replaced before the next card is drawn,whether the probability that is required is that three black cards are drawn after however many draws, or that three black cards are drawn in a sequence at some stage - but not necessarily the first three, or that the first three cards cards that are drawn are black.There is no information on any of these and so it is not possible to be certain about the answer.The probability of drawing three black cards, in three random draws - without replacement - from a standard deck, is 0.1176 approx.
There are 26 black cards in a deck of cards (13 spades and 13 clubs) There are 52 cards total in a deck of cards Therefore, the probability of drawing a black card from a deck of 52 cards: 26/52 0.5
The probability of drawing a red or black card from a standard deck of playing cards is 1 (a certainty). This is because these are the only options available.
1/26
There are 6 black face cards in a standard deck of 52 cards, so the probability of drawing a black face card in one try is 6/52 = 0.115
Of 26 black cards, 2 are aces... 1 in 13, or ~7.7%.
There are 2 red suits and 2 black suits. Therefore the probability of drawing a red card is 1/2. Or 50% chance.
1/2. or 50%. You can draw a red card, or you can draw a black card.However, if you have already drawn 10 black cards and 0 red cards then the probability of drawing a black is:16(remaning black cards)/42(remaning cards)=38%
after drawing the red card; deck status is:25 red and 26 black cards, total 51 cardsFirst part, drawing 13 black cards:probability of drawing 1st black card: 26/51probability of drawing 2nd black card: 25/50and so on .......till, probability of drawing 13th black card: 14/39overall probability= 26/51 * 25/50 * ...... 14/39Second part, drawing 13 red cards:probability of drawing 1st red card: 25/51probability of drawing 2nd red card: 24/50and so on .......till, probability of drawing 13th red card: 13/39overall probability = 25/51 * 24/50* ...... 13/39
Half the cards in a standard pack are black. Therefore the probability of drawing a black card is 1/2. Half the sides of a coin are "heads" so again the probability is 1/2. Therefore the probability you will both draw a black card and flip heads = 1/2 * 1/2 = 1/4.
(13*2+2)/52=0.53846
It is 8/52 or 2/13
2/52, which reduces to 1/26.
