The probability of drawing a king of hearts from a regular deck of cards is 1 in 52 because there is only one king of hearts in the standard 52 card deck.
1/26
It is 10/52 = 5/26.
The probability is 1/13 of drawing a king in one draw from a standard deck with no jokers.
The probability of drawing a king or a nine from a standard deck of 52 cards is (4 + 4) in 52, or 8 in 52, or 2 in 13, or about 0.1538.
The probability of drawing a king given that you drew a spade or a club is 2 out of 26, or 1 out of 13. This is because there are 2 kings (one from spades and one from clubs) out of a total of 26 spade and club cards.

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)
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 a jack is, P(J) = 1/13.The probability of drawing a queen is, P(Q) = 1/13.The probability of drawing a king is, P(K) = 1/13.The probability of drawing a jack or drawing a queen or drawing a king is;P(J or Q or K) = 1/13 + 1/13 + 1/13 = 3/13 = 0.23076923... ≈ 23.1%.
The probability of drawing a queen or king, in a single randomly drawn card, is 2/13. The probability of drawing one when you draw 45 cards without replacement is 1. The probability of choosing has nothing t do with the probability of drawing the card. I can choose a king but fail to find one!

(1 in 52) or about 0.01923.
There are 4 kings and 4 queens in a deck of 52 cards. The chance of drawing a king is 4 in 52 (or .077 in probability terms). The probability to draw either a king or a queen will be twice as high (.154)
The probability of drawing a king of hearts from a regular deck of cards is 1 in 52 because there is only one king of hearts in the standard 52 card deck.
The probability of drawing a jack and a king in that order from a standard deck is: P(J,K) = (4/52)∙(4/51) = 0.006033... ~ 0.006 ~ 0.6% The probability of drawing a jack and a king in any order is twice the above: P((J,K) or (K,J)) = 0.0112066... ~ 0.011 ~ 1.1%
