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.

There are two black 7's and two red queen's in a standard deck of playing cards. The probability of drawing a black 7 is 2 in 52, or 1 in 26, or about 0.038. The probability of drawing a red queen from the remaining 51 cards is 2 in 51, or about 0.039. The probability, then, or drawing a black 7 followed by a red queen is (2 in 52) times (2 in 51), which is 4 in 2652, or 2 in 1326, or about 0.00151.
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
The probability is one half.

There are 2 red suits and 2 black suits. Therefore the probability of drawing a red card is 1/2. Or 50% chance.

The probability of drawing a red heart is 1 in 4. This is the same as the probability of drawing a heart, as red is included as a superset of hearts.
Probability of not drawing a black six from a deck of cards = 1 - probability of drawing a black 6 = 1 - 2/52 = 50/52 = 25/26.
26:52 = 1:2
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 a red two from a standard deck of 52 cards is 2 in 52, or about 0.03846.
