One out of four.
The probability of drawing a Jack on the first draw from a standard deck of cards is 4 in 52. The probability of drawing a heart on the second draw is 13 in 51 (if the Jack was not a heart) or 12 in 51 (if the Jack was a heart). Multiply these two probabilities together, and you get 52 in 2652, or about 0.01961 for the case of the Jack not being a heart, and 48 in 2651, or about 0.01811 for the case of the Jack being a heart.
The probability of getting one heart in a random draw from a 52 card deck is 13 in 52, or 1 in 4. The probability of getting the second heart is 12 in 51 - the third, 11 in 50 - the fourth, 10 in 49. The total probability of getting four hearts is simply the product of those probabilities, or 1320 in 499800. Simplified to least common multiple, that reduces to 11 in 4165.
With a regular deck (2-Ace with ♥,♦,♣, and ♠), the probability of drawing a three is 1 in 13. The probability for a heart is 1 in 4, a.k.a. 25% or 1/4 . The probability for a 3 of hearts is 1 in 52.Improve:And to be more specific:because a heart is 25%, and a three is 4/52 % and the h of hearts is 1/52 getting a 3 OR heart is 25% (heart) + 7.69% (a 3) - 1.923% (3 of hearts can't be counted twice!) = .30767
There are 52 cards in a deck with no jokers. There are 13 hearts in such a deck so the probability of drawing a heart is13/52
The probability of getting the queen of hearts is 1 in 52, or about 0.01923. The probability of getting any queen is 4 in 52, or about 0.07692. The probability of getting any heart is 13 in 52, or exactly 0.25.
The probability of drawing a red heart is 1 in 4. This is the same as the probability of drawing a heart, as red is included as a superset of hearts.

It is 3/4.

13/52 = 1/4
Since the first card is red, that eliminates all spades and clubs, leaving the hearts and diamonds. If the first card is replaced then the probability is 1/2. If the first card is not replaced then the probability is 12/25 if the first card is a heart, or 13/25 if the first card is a diamond
This is a conditional probability, given the card is red, what is the chance it is a heart. Since there are 2 red hearts, the probability if 1/2
3/52*13/51+1/52*12/51= .01923
The probability of getting a particular suit (hearts, spades, diamonds, clubs) is 1 in 4. The probability of getting a card less than 8 (2, 3, 4, 5, 6, 7) is 6 in 13. The probability, then, of getting a particular suit less than 8 is (1 in 4) times (6 in 13) or 6 in 52 or 3 in 26.
