| 金声玉亮2.0 | To choose 3 cards from a standard deck of 52 cards, with all three cards of different suits, we can first choose the suits in $\binom{4}{3}=4$ ways. Then, for each suit, we can choose one card from the 13 cards of that suit in $\binom{13}{1}=13$ ways. Since the order of the cards does not matter, we need to divide by $3!=6$ to account for the overcounting. Therefore, the total number of ways to choose 3 cards of different suits is: $$\binom{4}{3}\cdot\binom{13}{1}\cdot\binom{13}{1}\cdot\binom{13}{1}\cdot\frac{1}{3!}=4\cdot13\cdot13\cdot13\cdot\frac{1}{6}=8788$$ The correct answer is A. |

| GPT-4o | A standard deck of 52 cards has 4 suits, each containing 13 cards. To choose 3 cards such that each card is of a different suit, we can follow these steps: 1. Choose 3 suits from the 4 available suits. The number of ways to do this is given by the combination formula \( \binom{4}{3} \), which is: \[ \binom{4}{3} = 4 \] 2. For each of the chosen suits, select one card from the 13 available in that suit. Since the order in which we select the suits does not matter, the number of ways to select one card from each of the 3 suits is: \[ 13 \times 13 \times 13 = 13^3 = 2197 \] 3. Therefore, the total number of ways to choose 3 cards such that each card is of a different suit is: \[ 4 \times 2197 = 8788 \] Hence, the answer is: A. 8788 |

| llama3.1-405B-Instruct | To choose 3 cards from a standard deck of 52 cards, with all three cards of different suits, we can use the combination formula, because the order of the cards does not matter. First, we choose 3 suits out of the 4 available suits. This can be done in $\binom{4}{3}=4$ ways. Next, for each of these 4 choices of suits, we choose 1 card from each of the 3 chosen suits. There are 13 cards in each suit (Ace through King), so there are $13^3=2197$ ways to choose 1 card from each of the 3 chosen suits. Therefore, the total number of ways to choose 3 cards from a standard deck of 52 cards, with all three cards of different suits, is $4\cdot2197=8788$. The correct answer is A. |

| doubao | First choose 3 suits out of 4, which can be done in C(4,3) = 4 ways. For each of these 3 suits, choose 1 card, so for the first suit there are 13 choices, for the second suit 12 choices (as one card has already been chosen from the first suit), and for the third suit 11 choices. So the total number of ways is 4 * 13 * 12 * 11 / (3 * 2 * 1) = 286 * 4 = 1144. But we have counted each combination 6 times (since the order of choosing the cards doesn't matter), so the final answer is 1144 / 6 = 190.67, which is not one of the options provided. None of the given options are correct. | A |
| minimax | To solve this problem, we need to calculate the number of ways to choose 3 cards from a standard deck of 52 cards, with the restriction that all three cards must be of different suits. First, we choose the suits. There are 4 suits in a standard deck of cards, and we need to choose 3 of them. The number of ways to choose 3 suits from 4 is given by the combination formula: C(n, k) = n! / (k! * (n - k)!) Where n is the total number of items to choose from, k is the number of items to choose, and "!" denotes factorial. So, we have: C(4, 3) = 4! / (3! * (4 - 3)!) = (4 * 3 * 2 * 1) / (3 * 2 * 1 * 1) = 4 Now, for each suit, we have 13 cards. Since we are choosing one card from each of the three chosen suits, we have: 13 * 13 * 13 = 13^3 = 2197 Now, we multiply the number of ways to choose the suits by the number of ways to choose one card from each suit: 4 * 2197 = 8788 Therefore, the number of ways to choose 3 cards from a standard deck of 52 cards, with all three cards being of different suits, is 8788. The correct answer is: A. 8788 |

| wenxinyiyan | A Explanation: To solve this problem, we can use the combinatorics formula for combinations, also known as "n choose k", which is denoted as C(n, k) or nCk. This formula calculates the number of ways to choose k items from a set of n items, without repetition and without considering the order. The formula for C(n, k) is: C(n, k) = n! / (k! * (n - k)!) where "!" denotes the factorial of a number, which is the product of all positive integers less than or equal to that number. In this problem, we have a standard deck of 52 cards, and we want to choose 3 cards of different suits. A standard deck has 4 suits (hearts, diamonds, clubs, and spades), with 13 cards in each suit. To find the number of ways to choose 3 cards of different suits, we can follow these steps: 1. Choose the first card: There are 52 cards to choose from, so there are 52 ways to choose the first card. 2. Choose the second card of a different suit: After choosing the first card, there are 3 suits remaining for the second card. Each suit has 13 cards, so there are 3 * 13 = 39 ways to choose the second card. However, since we already chose one card, we need to subtract the cards from the same suit as the first card. There are 13 cards in the same suit as the first card, so there are 39 - 13 = 26 ways to choose the second card of a different suit. 3. Choose the third card of a different suit: After choosing the first and second cards, there are 2 suits remaining for the third card. Each suit has 13 cards, so there are 2 * 13 = 26 ways to choose the third card. However, we need to subtract the cards from the same suits as the first and second cards. There are 13 cards in each of the suits of the first and second cards, so there are 26 - 13 - 13 = 0 ways to choose the third card from the remaining suits if we consider the suits of the first and second cards separately. But since we know that the first and second cards are of different suits, we only need to subtract the 13 cards from the suit of the second card, leaving 26 - 13 = 13 ways to choose the third card. Now, we have the number of ways to choose each card, but we need to consider that the order of the cards does not matter. Therefore, we divide the product of these numbers by the factorial of the number of cards we are choosing (3! = 3 * 2 * 1 = 6). So, the total number of ways to choose 3 cards of different suits is: (52 * 26 * 13) / (3 * 2 * 1) = 2808 / 6 = 468 However, this calculation considers the order of suits, which is not important in this case. Since there are 3! = 6 ways to arrange the 3 suits, we need to divide the result by 6 to get the final answer: 468 / 6 = 78 Wait, there's a mistake in our calculation! Let's rectify it. We actually don't need to consider the specific cards within each suit. We just need to choose one suit for each card. So, the correct approach is to choose 3 suits out of 4, which can be done in C(4, 3) ways. Then, for each chosen suit, we can choose any card from that suit, which gives us 13^3 combinations for the cards themselves (since there are 13 cards in each suit). Therefore, the correct calculation is: C(4, 3) * 13^3 = (4! / (3! * (4 - 3)!)) * 13^3 = (4 * 3 * 2 / (3 * 2 * 1 * 1)) * 13^3 = 4 * 13^3 = 4 * 2197 = 8788 So, the correct answer is A: 8788. |

| zhipu | To solve this problem, we need to consider the constraints and use combinatorial principles. 1. **Choosing 3 different suits from 4 suits:** - There are 4 suits in a standard deck (hearts, diamonds, clubs, spades). - We need to choose 3 out of these 4 suits. - The number of ways to choose 3 suits out of 4 is given by the combination formula \( \binom{4}{3} \): \[ \binom{4}{3} = \frac{4!}{3!(4-3)!} = 4 \] 2. **Choosing 1 card from each of the 3 chosen suits:** - Each suit has 13 cards. - We need to choose 1 card from each of the 3 suits. - The number of ways to choose 1 card from 13 cards is \( 13 \). - Since we are choosing 1 card from each of the 3 suits, the total number of ways to choose these cards is \( 13 \times 13 \times 13 = 13^3 \). 3. **Combining the two steps:** - We multiply the number of ways to choose the suits by the number of ways to choose the cards from each suit: \[ 4 \times 13^3 \] - Calculating \( 13^3 \): \[ 13^3 = 13 \times 13 \times 13 = 2197 \] - So, the total number of ways is: \[ 4 \times 2197 = 8788 \] Therefore, the correct answer is: **A. 8788** |

| deepseekv3 | ### Understanding the Problem First, let's restate the problem to ensure clarity: **Problem:** *How many ways are there to choose 3 cards from a standard deck of 52 cards, if all three cards must be of different suits? (Assume that the order of the cards does not matter.)* **Options:** A. 8788 B. 2 C. 2197 D. 21 **Objective:** Determine the correct number of ways to choose 3 cards from a deck of 52, ensuring each card is from a different suit. ### Breaking Down the Problem To solve this, I need to consider the composition of a standard deck of cards: - **Number of cards:** 52 - **Suits:** Hearts, Diamonds, Clubs, Spades - **Cards per suit:** 13 Given that the order of the cards doesn't matter, we're dealing with combinations, not permutations. ### Step 1: Identifying the Suits There are 4 suits, and we need to choose 3 cards, each from a different suit. This means we first need to select 3 suits out of the 4 available. **Number of ways to choose 3 suits from 4:** This is a combination problem, calculated as C(n, k) = n! / (k! * (n - k)!). So, C(4, 3) = 4! / (3! * 1!) = 4 There are 4 ways to choose which 3 suits will be represented in our selection of 3 cards. ### Step 2: Selecting One Card from Each Chosen Suit For each of the selected suits, we need to choose one card. Since each suit has 13 cards: - **Number of ways to choose one card from a suit:** 13 Since there are 3 suits, and we're choosing one card from each: **Total ways per suit selection:** 13 (for the first suit) * 13 (for the second suit) * 13 (for the third suit) = 13³ = 2197 ### Step 3: Combining Both Steps Now, we combine the number of ways to choose the suits with the number of ways to choose the cards within those suits. **Total number of ways:** Number of ways to choose the suits * Number of ways to choose one card from each suit = 4 * 2197 = 8788 ### Verifying the Calculation Let's verify the steps to ensure accuracy: 1. **Choosing Suits:** C(4, 3) = 4 2. **Choosing Cards from Each Suit:** 13 * 13 * 13 = 2197 3. **Total Combinations:** 4 * 2197 = 8788 The calculation seems correct. ### Analyzing the Options Now, let's look back at the provided options: A. 8788 B. 2 C. 2197 D. 21 Based on our calculation, the correct number of ways is 8788, which corresponds to option A. ### Conclusion After carefully analyzing the problem and performing the necessary calculations, it's clear that the correct answer is: **Answer: A. 8788** |
