total of 10 items they can be arranged in 10! ways but, 7 bands are identical, so there would be no change if they are arranged in any way, similarly with 3 floats.
Hence total number of ways =10!7!×3!=8×9×106=120 ways.

You can type blindfold at your keyboard, but that comes at a disadvantage of making typos. Let us say that you are required to type the word FLASH. You might insert anextra letter (all 26 letters equally likely) with probability 0.1, skip any required letter with probability 0.1, or write the correct required letter with probability 0.8. What is the probability that, when required to type the word FLASH, you instead end up writing FAST?
Hint:
- Letters F, A, S are correct required letters
- L and H are skipped letters
- T is the extra letter
