To solve permutation problems involving repeated elements, we use the formula:
Number of distinct permutations = Total permutations of all letters ÷ (Product of factorials of the counts of each repeated letter)
Example (Common Problem: "MISSISSIPPI")
Let’s assume the problem refers to the word "MISSISSIPPI" (a typical permutation problem with repetition):
- Total letters: 11
- Repeated letters: I (4 times), S (4 times), P (2 times), M (1 time)
Calculation:
[
\frac{11!}{4! \times 4! \times 2!} = \frac{39916800}{24 \times 24 \times 2} = 34650
]
Answer: 34650
If the problem refers to a different word, please provide the word or letter counts for an exact solution.
\boxed{34650}
