It is 6/26 = 3/13
Excluding jokers, the probability is 1 in 2.
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.
The probability of drawing one black seven from a standard deck of cards is 2/52 = 1/26. The probability of drawing the other black seven from the remaining 51 cards is 1/51. Therefore the probability of drawing both black sevens from a deck of cards = 1/26 x 1/51 = 1/1326 ~ 0.000754 (3sf).
Of 26 black cards, 2 are aces... 1 in 13, or ~7.7%.
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.
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.
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.
The probability of drawing one black seven from a standard deck of cards is 2/52 = 1/26. The probability of drawing the other black seven from the remaining 51 cards is 1/51. Therefore the probability of drawing both black sevens from a deck of cards = 1/26 x 1/51 = 1/1326 ~ 0.000754 (3sf).
The probability of drawing three black cards one at a time with replacement from a standard deck of 52 cards is 1/3x1/2x26/52, which is 0.833.
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.
There are 2 red suits and 2 black suits. Therefore the probability of drawing a red card is 1/2. Or 50% chance.
Of 26 black cards, 2 are aces... 1 in 13, or ~7.7%.
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.
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.
The probability is one half.
