| 金声玉亮2.0 | To find the number of different 6-letter arrangements that can be made from the letters in the word BANANA, we need to take into account the repetition of the letters. The word BANANA has 6 letters in total, with the letter 'A' appearing 3 times, and the letters 'B', 'N' appearing once each. The formula for permutations with repetition is given by: \[P = \frac{n!}{n_1! \cdot n_2! \cdot \ldots \cdot n_k!}\] where: - \(n\) is the total number of items, - \(n_1, n_2, \ldots, n_k\) are the counts of each type of repeated item. In this case: - \(n = 6\) (total number of letters), - \(n_1 = 3\) (the number of 'A's), - \(n_2 = 2\) (the number of 'N's), and - \(n_3 = 1\) (the number of 'B's). Substituting these values into the formula, we get: \[P = \frac{6!}{3! \cdot 2! \cdot 1!}\] Calculating the factorials: \[6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 720\] \[3! = 3 \times 2 \times 1 = 6\] \[2! = 2 \times 1 = 2\] Substituting these values back into the formula: \[P = \frac{720}{6 \cdot 2 \cdot 1} = \frac{720}{12} = 60\] Thus, the number of different 6-letter arrangements that can be made from the letters in the word BANANA is 60. |

| deepseekr1 | To determine the number of different 6-letter arrangements that can be made from the letters in the word BANANA, we start by noting the frequency of each letter: B appears once, A appears three times, and N appears twice. The formula for permutations of a multiset is given by: \[ \frac{n!}{n_1! \cdot n_2! \cdot \ldots \cdot n_k!} \] where \( n \) is the total number of letters, and \( n_1, n_2, \ldots, n_k \) are the frequencies of the repeated letters. For the word BANANA, we have: - \( n = 6 \) - \( n_1 = 3 \) (for the letter A) - \( n_2 = 2 \) (for the letter N) - The letter B is unique, so its factorial is 1!. Plugging these values into the formula: \[ \frac{6!}{3! \cdot 2! \cdot 1!} = \frac{720}{6 \cdot 2 \cdot 1} = \frac{720}{12} = 60 \] Thus, the number of different 6-letter arrangements that can be made from the letters in BANANA is \(\boxed{60}\). |

| gpto1 | To find the number of different 6-letter arrangements that can be made from the letters in the word **BANANA**, we need to consider the repeated letters. **Step 1: Identify the letters and their frequencies.** The word **BANANA** consists of the following letters: - **A** appears **3** times. - **N** appears **2** times. - **B** appears **1** time. **Step 2: Use the formula for permutations with repetitions.** When arranging objects where some are identical, the number of unique arrangements is given by the formula: \[ \text{Number of arrangements} = \dfrac{n!}{n_1! \times n_2! \times n_3! \times \ldots} \] where: - \( n \) is the total number of items. - \( n_1, n_2, n_3, \ldots \) are the frequencies of each distinct item. **Step 3: Plug in the values.** For **BANANA**: - Total letters \( n = 6 \). - Frequency of **A**: \( n_1 = 3 \). - Frequency of **N**: \( n_2 = 2 \). - Frequency of **B**: \( n_3 = 1 \) (since \(1! = 1\), it doesn't affect the calculation). Now, apply the formula: \[ \text{Number of arrangements} = \dfrac{6!}{3! \times 2!} \] **Step 4: Calculate the factorials.** Calculate the factorials: - \( 6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 720 \) - \( 3! = 3 \times 2 \times 1 = 6 \) - \( 2! = 2 \times 1 = 2 \) **Step 5: Compute the number of arrangements.** \[ \text{Number of arrangements} = \dfrac{720}{6 \times 2} = \dfrac{720}{12} = 60 \] **Answer:** There are **60** different 6-letter arrangements that can be made from the letters in the word **BANANA**. |

| baichuan4 | To find the number of different 6-letter arrangements that can be made from the letters in the word "BANANA," we need to consider the total number of permutations possible, taking into account the repeated letters. The word "BANANA" consists of 6 letters, with 3 A's, 2 N's, and 1 B. We can calculate the number of arrangements using the formula for permutations with repetition: \[ P(n, r) = \frac{n!}{n_1! \cdot n_2! \cdot ... \cdot n_k!} \] where: - \( n \) is the total number of items (in this case, 6 letters) - \( r \) is the number of items being selected (in this case, 6 letters as well) - \( n_1, n_2, ..., n_k \) are the frequencies of each distinct item (in this case, 3 A's, 2 N's, and 1 B) Substituting our values: \[ P(6, 6) = \frac{6!}{3! \cdot 2! \cdot 1!} \] \[ P(6, 6) = \frac{720}{6 \cdot 2 \cdot 1} \] \[ P(6, 6) = \frac{720}{12} \] \[ P(6, 6) = 60 \] Therefore, there are 60 different 6-letter arrangements that can be made from the letters in the word "BANANA." |

| minimax | To solve this problem, we need to calculate the number of different arrangements of the letters in the word "BANANA," which has 6 letters with the following counts of identical letters: 3 As, 2 Ns, and 1 B. The formula for the number of arrangements of n objects where there are n1 identical objects of one type, n2 identical objects of another type, ..., nk identical objects of the k-th type is: n! / (n1! * n2! * ... * nk!) In this case, n = 6 (total number of letters), n1 = 3 (number of As), and n2 = 2 (number of Ns). There is only one B, so it doesn't affect the calculation since 1! = 1. Using the formula, we get: 6! / (3! * 2!) = (6 * 5 * 4 * 3 * 2 * 1) / ((3 * 2 * 1) * (2 * 1)) = (6 * 5 * 4) / (2) = 120 / 2 = 60 So, there are 60 different 6-letter arrangements that can be made from the letters in the word "BANANA." |

| kimi | To solve this problem, we need to calculate the number of unique permutations of the letters in the word "BANANA" when forming 6-letter arrangements. The word "BANANA" consists of 6 letters where: - B appears 1 time - A appears 3 times - N appears 2 times When calculating permutations of a multiset (a set with repeated elements), we use the formula: \[ \text{Permutations} = \frac{n!}{n_1! \cdot n_2! \cdot \ldots \cdot n_k!} \] where \( n \) is the total number of items to arrange, and \( n_1, n_2, \ldots, n_k \) are the frequencies of the distinct items. For "BANANA": - \( n = 6 \) (total letters) - \( n_1 = 1 \) (for B) - \( n_2 = 3 \) (for A) - \( n_3 = 2 \) (for N) So the number of different 6-letter arrangements is: \[ \frac{6!}{1! \cdot 3! \cdot 2!} \] Calculating the factorials: \[ 6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 720 \] \[ 1! = 1 \] \[ 3! = 3 \times 2 \times 1 = 6 \] \[ 2! = 2 \times 1 = 2 \] Now plug these values into the formula: \[ \frac{720}{1 \cdot 6 \cdot 2} = \frac{720}{12} = 60 \] So there are 60 different 6-letter arrangements that can be made from the letters in the word "BANANA". |

| wenxinyiyan | To solve this problem, we need to understand the concept of permutations with repetitions. The word BANANA consists of 3 A's, 1 B, and 2 N's. The total number of arrangements can be calculated using the formula for permutations with repetitions, which is: Total arrangements = (Number of ways to arrange all letters) / (Number of ways to arrange the repeated letters) In this case, the calculation would be: Total arrangements = (6!) / (3! * 2!) where 6! is the factorial of 6, 3! is the factorial of 3, and 2! is the factorial of 2. Calculating this, we get: Total arrangements = (720) / (6 * 2) = 720 / 12 = 60 So, there are 60 different 6-letter arrangements that can be made from the letters in the word BANANA. |

The word "BANANA" consists of 6 letters where 'A' appears 3 times and 'N' appears 2 times, while 'B' appears once. The formula for finding the number of permutations of a multiset is: \[ \frac{n!}{n_1! \times n_2! \times \cdots \times n_k!} \] Where: - \( n \) is the total number of items to arrange. - \( n_1, n_2, \ldots, n_k \) are the frequencies of the distinct items.
