In how many ways can you rearrange the letters A, B, C, D, E?
The total number of linear arrangements obtained from
n=5 different letters A,B,C,D,E is given as
nPn
=5P5
=5!×4!×3!×2!×1!
=120
Hence number of the way to arrange A, B,C,D,E are 120.
* if you can obtain n number of different thing in this process.
number of way is 120
