There are 6 black face card in a deck of 52 cards, so the probability of getting a black face card is 6/52 = 3/26
1/26
28/52
It is 3/13. The fact that the card is black makes no difference since the probability is the same for both colours.
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
There are 6 black face card in a deck of 52 cards, so the probability of getting a black face card is 6/52 = 3/26
The probability of getting a red card out of a standard 52 card deck is 26 in 52, or 0.5. The probability of getting a second red card is 25 in 51, or 0.490, because one red card is missing, and the deck is short by one card. The probability of getting a black card next is 26 in 50, or 0.52, because the deck is short by two cards, but all the black cards are there. Multiply these probabilities together, and you get about 0.127, or about 1 in 8, so the probability of getting 2 red cards and then a black card in a random 52 card deck is about 1 in 8.

There are 6 black face cards in a standard deck of 52 cards, so the probability of drawing a black face card in one try is 6/52 = 0.115

It is 3/13. The fact that the card is black makes no difference since the probability is the same for both colours.
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

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.
In a 52 card, 4 suit deck, the probability of selecting a heart is 13/52 or 1/4.
If you randomly pick a card from a standard deck of cards, that probability will be 1/4, since 1/4 of the cards are heart.
