Final answer:
To find the total number of different 10-letter arrangements using the letters in REPARATION, apply the concept of permutations considering repeated letters.
Explanation:
To find the total number of different 10-letter arrangements that can be formed using the letters in the word REPARATION, we need to consider the repeated letters.
- Firstly, there are 10! total ways to arrange the letters.
- Then, we divide by the repeated letters. In REPARATION, 'R' appears 2 times, 'A' appears 2 times, and 'E' appears 2 times.
- Therefore, the total number of different 10-letter arrangements is 10! / (2! 2! 2!).
