What is the probability of drawing an ace or a diamond?
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 is the probability of drawing the king of spades?
(1 in 52) or about 0.01923.
What is the probability of selecting the ace of spades from a deck of cards?
From a 52 card deck, probability is 1/52.
What is the probability of drawing an ace of spades and a heart from a deck of cards in two successive draws without placing the first card back in the deck of 52?
There's only one Ace of spades in a 52 card deck so it's 1/52 times the probability of drawing a heart (there are 13 hearts in the same deck, but now there are 51 cards because we already drew one out). That makes it 1/52 * 13/51 = 13/2652 = 1/204 This is if you want the Ace first, then the heart, if order doesn't matter, you add this to the probability of drawing the heart first, then the Ace of Spades which is (13/52*1/51) =1/204 notice is the same as the first one. So if order doesn't matter, the probability is 1/204 + 1/204 = 2/204 = 1/102
What is the Probability of drawing two spades out of 52 cards?
The probability of drawing a spade in a standard 52 card deck is 13 in 52, or 1 in 4. The probability of drawing a second spade, assuming the first spade was not replaced back into the deck, is 12 in 51. The probability, then, of drawing two spades is the product of those two probabilities, or 12 in 204, or 1 in 17.
