It should be 20 out of 52 if Ace is included as a number card.
Not including ace the probability is 18 out of 52.

∙ 11y agoWhat is the probability of drawing 3 red cards (hearts or diamonds) from a standard 52-card deck? Enter your answer as a number rounded to 2 decimal places.
The probability of NOT drawing a face card form a standard deck of 52 cards is 40 in 52, or 10 in 13.
It is 8/52 or 2/13
The probability of drawing the first face card is 12 in 52. The probability of drawing the second is 11 in 51. The probability of drawing the third is 10 in 50. Thus, the probability of drawing three face cards is (12 in 52) times (11 in 51) times (10 in 50) or (1320 in 132600) or about 0.009955.
If you draw 9 or fewer cards, the probability is 0. If you draw 10 or more card, the probability is 1.

What is the probability of drawing 3 red cards (hearts or diamonds) from a standard 52-card deck? Enter your answer as a number rounded to 2 decimal places.
Since 1/2 of the cards are red, the probability of drawing a red card is 1/2 or 0.5.
The probability of NOT drawing a face card form a standard deck of 52 cards is 40 in 52, or 10 in 13.
It is 20/52 or 5/13.
It is 8/52 or 2/13
The probability of drawing the first face card is 12 in 52. The probability of drawing the second is 11 in 51. The probability of drawing the third is 10 in 50. Thus, the probability of drawing three face cards is (12 in 52) times (11 in 51) times (10 in 50) or (1320 in 132600) or about 0.009955.
The probability of drawing a diamond is a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.
If you draw 9 or fewer cards, the probability is 0. If you draw 10 or more card, the probability is 1.
26/52(number of red cards)+2/52(number of king left)=28/52
In order to determine the probability of drawing 2 hearts and then a spade, in that order, from a deck of 52 cards, start by considering the first card. The probability of drawing a heart is 1 in 4. Since you have now reduced the number of hearts and the number of cards in the deck by one, the probability of drawing another heart is 4 in 17. Since you have further reduced the number of cards by one, the probability of drawing a spade is 13 in 50. Multiply these probabilities together, (1/4) (4/17) (13/50), and you get about 0.0153, or about 153 in 10000.
