# How many arrangements in a row of no more than three letters can be formed using the letters of the word NETWORK (with no repetitions allowed)?

To determine

To find how many arrangements in a row of no more than three letters can be formed using the letters of the word NETWORK (with no repetitions allowed).

Explanation

Given information:

The objective is to find tile number of arrangements of no more than three letters formed using the letters of the word NETWORK.

Concept used:

p(n,r)=n!nr!

Calculation:

The objective is to find tile number of arrangements of no more than three letters formed using the letters of the word NETWORK.

The word NETWORK contains 7 letters, the number of arrangements taking one at a time is P(7,1)=7!(71)!.

The number of arrangements taking one at a time is P(7,2)=7!(72)!.

The number of arrangements taking one at a time is P(7,3)=7!(73)!
