1/26
Probability of drawing a black 7 from a standard 52-card deck is 2/52 or 1/26.

# of diamond card = 13 # of black 7 card = 2 P(diamond and black 7) = 13/52 * 2/51 = 1/4 * 2/51 Answer = 1/102
Probability of drawing a 7 or 9 is the probability of draw a 7 plus the probability of draw a 9 which is 4/52 + 4/52 = 8/52 = 2/13 = 0.1538.
If you draw more than 24 cards from a standard pack, without replacement, the probability is 1. That is, it is a certainty. The probability of the outcome for a single, randomly drawn card from a standard pack, is 7/13.
Probability of drawing a black 7 from a standard 52-card deck is 2/52 or 1/26.

There are 4 nines in a 52 card deck so the probability of drawing a nine is 4/52 or 1/13. Which is 7%
# of diamond card = 13 # of black 7 card = 2 P(diamond and black 7) = 13/52 * 2/51 = 1/4 * 2/51 Answer = 1/102
The probability of doing so, if the first card is not replaced, is 0.0385, approx.
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.
There are 2 black queens and 26 red cards in a standard deck. Therefore the probability is 28/52 = 7/13 = 53.85%
7/26
The probability of drawing an ace and then a seven from a standard deck of 52 card is (4 in 52) times (4 in 51), or 16 in 2652, or 4 in 663, or about 0.006033.
The probability of drawing a seven from a standard 52 card deck is 4 in 52, or 1 in 13, or about 0.07692.
It is 28/52 = 7/13
Probability of drawing a 7 or 9 is the probability of draw a 7 plus the probability of draw a 9 which is 4/52 + 4/52 = 8/52 = 2/13 = 0.1538.
