The Fundamental Counting Principle$:$
The number of ways in which a series of successive things can occur is found by multiplying the number of ways in which each thing can occur.
-----------
The 1st sentence can be chosen in $1$ ways.
The 5th sentence can be chosen in $1$ ways.
Once a sentence is chosen, there is one less left to choose from.
The 2nd, 3rd, and 4th sentences are arranged from the three that are left over.
1. The 1st sentence can be chosen in $1$ ways.
2. The 2nd sentence can be chosen in $3$ ways.
3. The 3rd sentence can be chosen in $2$ ways.
4. The 4th sentence can be chosen in $1$ ways.
5. The 5th sentence can be chosen in $1$ ways.
Total ways to arrange the sentences:
$1\times 3\times 2\times 1\times 1=3!=6$
