What is the probability of drawing a face card given that the card is red?
It is 3/13, and the colour of the suit is irrelevant.

Out of a standard 52 card deck what is the probability of drawing a heart given that a red card was drawn first?
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 7 balls in a box 3 black and 4 red a ball will be drawn and not replacecd then a second ball wil lbe drawn what is the chances it will be a black ball and then red ball?
The probability of getting on the first draw a black ball is: P(B1) = 3/7. The probability of getting a red ball given the event of drawing a black ball on the first draw is: P(R2│B1) = 4/6. The probability of drawing a black ball on the first draw and a red ball on the second draw is: P(B1UR2) = P(B1)∙P(R 2│B1) = (3/7)∙(4/6) = 0.2857... ~ 0.286 ~ ~ 28.6%
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 that the first card drawn is a spade given that the second card drawn is a spade?
It is 156/663 = 0.2353, approx.

What is the probability of drawing 3 cards that are all queens from a deck of cards?
Aprox. 0.018%There are 4 queens in a regular deck of 52 cards.The probability of drawing a queen on the first draw is: P(Q1) = 4/52.The probability of drawing a queen on the second draw given that the first card wasa queen is: P(Q2│Q1) = 3/51.The probability of drawing a queen on the third draw given that the first two cardswere queens is: P(Q3│(Q2UQ1)) = 2/50.The probability of drawing 3 queens on the first 3 cards drawn from a deck of cardsis: P(Q1UQ2UQ3) = (4/52)∙(3/51)∙(2/50) = 1.80995... x 10-4 ≈ 0.00018 ≈ 0.018%
What is the probability of drawing a diamond or a red card from a 52 card deck?
"Neither card is red" is the same as "both cards are black". The probability that the first card is black is 26 out of 52, or 1/2. Given that the first card is black, there are 51 cards remaining, of which 25 are black; thus the conditional probability that the second card is also black is 25/51. The probability that both cards are black is the product of these two probabilities: 1/2 * 25/51 = 25/102, or about 24.51%.
If a single card is drawn from a 52 card deck what is the probability its a face card given that it is a king?
Given that it is a king, the probability that it is a face card is 100%. All Kings are face cards.
If a single card is drawn from a 52 card deck what is the probability its a face cad given that it is a king?
100%
Given an ordinary deck of cards what is the probability that a single card drawn would be an ace?
The answer is 1:13
What is the probability of drawing a face card given that the card is red?
It is 3/13, and the colour of the suit is irrelevant.
