"Neither card is red" is the same as "both cards are black". The probability that the first card is black is 26 out of 52, or 1/2. Given that the first card is black, there are 51 cards remaining, of which 25 are black; thus the conditional probability that the second card is also black is 25/51. The probability that both cards are black is the product of these two probabilities: 1/2 * 25/51 = 25/102, or about 24.51%.
The probability of drawing a diamond is a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.
number of cards in a deck =52 number of cards that are not diamond =39 Probability that the card drawn is not a diamond= 39/52 = 3/4
In a standard 52 card deck, the probability of drawing an ace is 1/13, and the probability of drawing a diamond is 1/4. The probability of drawing both an ace and a diamond is 1/52.Thus the probability of drawing an ace or a diamond is1/13 + 1/4 - 1/52 = 4/13 or about .308.
what are the odds in favor of drawing a diamond from an ordinary deck
Probability of drawing a seven of spades, from a 52 card deck, is 1/52.
The probability of drawing a diamond from a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.
The probability of drawing a king is 4:52The probability of drawing a diamond is 13:52 (or 1:4)The probability of drawing a king (0.07692...) then replacing that king into the deck then drawing a diamond is 0.019230769.If you leave the king out, the probability will be slightly greater (4/52) * (13/51)Unless the king you left out of the deck was a king of diamonds, in which case, the probability would be (4/52) * (12/51)
To determine the probability that one card drawn is a club and the other is a diamond from a standard deck of 52 cards, you can use the concept of combinations. There are 13 clubs and 13 diamonds in the deck. The probability of drawing one club and one diamond in two draws (without replacement) can be calculated as follows: the probability of drawing a club first and then a diamond is (13/52) * (13/51), and the probability of drawing a diamond first and then a club is (13/52) * (13/51). Adding these two probabilities gives you the total probability of one card being a club and the other a diamond. The final probability is approximately 0.25 or 25%.
The probability of drawing a queen, from a 52 card deck, is 4/52 or 1/13.
The probability of NOT drawing a face card form a standard deck of 52 cards is 40 in 52, or 10 in 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%
