If you draw 40 cards without replacement the probability is 1!
If you draw just one, the probability is 1/4.
The probability of drawing a 10 or a diamond out of 52 cards is 16 in 52, or 4 in 13. There are 4 tens and 13 diamonds, but one ten is also a diamond, so there are 16 cards that are a ten or a diamond.
Since there are 4 aces is a normal deck of 52 cards, the probability of drawing an ace is 4 in 52, or 1 in 13.
The probability of drawing two diamonds from a deck of cards is (13 in 52) times (12 in 51), or 156 in 2,652, or 78 in 1,327.
The probability of drawing a 2, 3, or 4 from a standard deck of 52 cards is (3 times 4) in 52, or 12 in 52, or 2 in 13, or about 0.1538.
The probability of drawing a pair from a standard deck of 52 cards is 3 in 51, or 1 in 17, or about 0.0588.
The probability of drawing a diamond is a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.
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 10 or a diamond out of 52 cards is 16 in 52, or 4 in 13. There are 4 tens and 13 diamonds, but one ten is also a diamond, so there are 16 cards that are a ten or a diamond.
what are the odds in favor of drawing a diamond from an ordinary deck
For a normal deck of cards, the answer is none.
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
Since there are 4 aces is a normal deck of 52 cards, the probability of drawing an ace is 4 in 52, or 1 in 13.
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)
The probability on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.
It is 16/52 = 4/13 or 0.3077
The probability, if you draw 40 cards, without replacement, is 1. That is, it is a certainty. The probability on a single random draw is 1/4.
You need to state a problem. If for example you ask what is the probability of drawing a heart or diamond in a single draw from a standard deck of 52 cards the answer would be .5
