13 to 1
The probability of drawing the Ace of Hearts from a standard deck of 52 cards is 1 in 52. The probability of then drawing the Ace of Diamonds is then 1 in 51. Multiply these two probabilities together, and you get 1 in 2652, or about 0.0003771.The probability of drawing the ace of hearts from a deck before drawing the ace of diamonds, ignoring any other cards, is 1/2.Note: Both of these answers are correct. It depends on your point of view. They've been left so that you, dear reader, can think about it.
The probability of drawing two specific cards from a standard deck of 52 cards is (1 in 52) times (1 in 51), or 1 in 2652, or about 0.0003771.

The probability of drawing a diamond from a standard 52-card poker deck without jokers is 13/52, or 1/4. The probability of drawing a second diamond at that point would then be 12/51, for an overall probability of 12/212, or 3/53. This amounts to about a 5.88% chance.
The probability of drawing three diamonds from a standard deck of 52 cards is (13 in 52) times (12 in 51) times (11 in 50), or 1716 in 132600, or about 0.01294.

Not necessarily. The probability of a complementary event with probability p is 1-p. Two mutually exclusive events, however, don't necessarily add up to a probability of 1. For example, the probability of drawing a King from a standard deck of cards is 1 in 13, which the complementary probability of not drawing a King is 12 in 13. The probability, however, of drawing a Heart is 1 in 4, while the probability of drawing a Club is also 1 in 4. That leaves Diamonds and Spades, which account for the remaining probability of 2 in 4.
The probability of drawing the queen of hearts is 1 in 52, or about 0.01923.
