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

What is the probability drawing an ace followed by a king?
If only two cards are drawn from a standard deck of cards, with the first card replaced before drawing the second, the answer is 0.005917 (approx). If the first card is not replaced, the probability increases to 0.006033.
What is the probability of drawing 3 black cards (spades or clubs) from a standard 52-card deck?
The probability of drawing three black cards from a standard pack depends on:whether the cards are drawn at random,whether or not the drawn cards are replaced before the next card is drawn,whether the probability that is required is that three black cards are drawn after however many draws, or that three black cards are drawn in a sequence at some stage - but not necessarily the first three, or that the first three cards cards that are drawn are black.There is no information on any of these and so it is not possible to be certain about the answer.The probability of drawing three black cards, in three random draws - without replacement - from a standard deck, is 0.1176 approx.
What is the probability of drawing two red queens in a pack of playing cards?
The answer depends on how many cards are drawn, whether that is with or without replacement, whether the cards are drawn at random. If only one card is drawn, the probability is 0. If 51 cards are drawn, the probability is 1. If two cards are drawn, at random, and the first is not replaced, the probability is (2/52)*(1/51) = 2/2652 = 0.00075, approx.
What is the probability of drawing a club and a 9 from a deck of 52 playing cards?
The answer depends on whether or not the card is drawn randomly and also, whether or not the card drawn in the first attempt is replace.
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.

John and Martha are playing cards with a standard deck of 52 cards with 4 suits What is the probability of the first card drawn being a heart?
If the card is drawn randomly, the probability is 1/4.

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.
What is the probability of drawing 2 cards that are a 2 from a deck of 52?
The probability of drawing 2 cards that are two's from a standard deck of 52 playing cards is 1 in 221. The probability of drawing the first two is 4 in 52 or 1 in 13. The probability of drawing the second two is 3 in 51. Multiply those two probabilities together and you get 3 in 663, or 1 in 221.
A pack of cards is shuffled and one is drawn out at random 80 times what is the probability of drawing a spade?
Given the way you have worded the question I take it to mean, what is the probability of drawing at least one spade?We can do this most easily by asking first, what is the probability of drawing no spades on each of the 80 times. This is 39/52. The probability of doing this 80 times is (39/52)80.Then the probability of not doing this is 1 - (39/52)80, which is quite close to one. The probability of drawing at least one spade is almost one.
What is the probability of drawing two 10s in card deck?
Clearly, it is necessary to draw at least two cards. How many are drawn? Are the cards drawn at random? Is the first replaced before drawing the second? Please edit the question to include more context or relevant information.
What is the probability of drawing three aces in a row without replacement?
The probability of drawing aces on the first three draws is approx 0.0001810
What is the probability of drawing at least one ace from a poker deck on two draws if the first card is replaced before the second card is drawn?
The probability of drawing a red card and a spade in two cards is the probability of drawing a red card multiplied by the probability of drawing a spade, multiplied by 2 (as it doesn't matter which way around they are drawn). The probability of drawing a spade is 1/13 as there are 4 spades and 52 cards. The probability of drawing a red card after this is 26/51 if the spade was black, and 25/51 if the spade was red. This averages at 51/102 Multiply these probabilities together and then multiply by two and we get 51/663 which can be simplified to 1/13
What is the probability of drawing at least one ace from a poker deck on two draws if the first card is replaced before the second drawn?
2 in 52, or 1 in 26, or about 0.03846.
