Step-by-step explanation:
- So the word is REMAND and the arrangement of letters has to be found.
- Now when there are no limitations for the arrangement we get
- 6 P 6
- 6!
- Factors will be 6 x 5 x 4 x 3 x 2 x 1
- = 720
- When the word begins with RE we have
- 4 P 4
- 4!
- Factors will be 4 x 3 x 2 x 1
- = 24
- When the word does not begin with RE we get
- 6! – 4! = 720 – 24
- = 696
