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.
Excluding jokers, the probability is 1 in 2.
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

It is 8/13.
it is a 1/4
1/26
The probability of drawing a black 8 from a standard deck of 52 card is 2 in 52 or 1 in 26 or about 0.03846.
Probability of drawing a black 7 from a standard 52-card deck is 2/52 or 1/26.
Excluding jokers, the probability is 1 in 2.
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.
1/26
There are 2 red suits and 2 black suits. Therefore the probability of drawing a red card is 1/2. Or 50% chance.
