Probability of drawing a red card:
To find the probability of drawing a red card, we need to determine the total number of red cards in the deck and divide it by the total number of cards in the deck.
- Total number of red cards: There are two red suits in a deck, which are hearts and diamonds. Each suit contains 13 cards, so the total number of red cards is 13 + 13 = 26.
- Total number of cards in the deck: A standard deck of 52 cards contains 26 red cards and 26 black cards.
Therefore, the probability of drawing a red card is:
P(Red card) = Number of red cards / Total number of cards = 26 / 52 = 1/2 = 0.5
Probability of drawing a number card:
To find the probability of drawing a number card, we need to determine the total number of number cards in the deck and divide it by the total number of cards in the deck.
- Total number of number cards: In each suit (hearts, diamonds, clubs, and spades), there are 9 number cards (2, 3, 4, 5, 6, 7, 8, 9, 10). Since there are four suits, the total number of number cards is 9 * 4 = 36.
- Total number of cards in the deck: A standard deck of 52 cards contains 36 number cards and 16 face cards (4 Jacks, 4 Queens, 4 Kings, and 4 Aces).
Therefore, the probability of drawing a number card is:
P(Number card) = Number of number cards / Total number of cards = 36 / 52 = 9/13 ≈ 0.692
Explanation:
- The probability of drawing a red card is 1/2 or 0.5. This means that out of every two cards drawn from a well-shuffled deck, one of them is expected to be a red card on average.
- The probability of drawing a number card is 9/13 or approximately 0.692. This means that out of every 13 cards drawn from a well-shuffled deck, around 9 of them are expected to be number cards on average.
Summary:
- The probability of drawing a red card from a well-shuffled deck is 1/2 or 0.5.
- The probability of drawing a number card from a well-shuffled deck is 9/13 or approximately 0.692.
