The number of ways to arrange 12 jurors willbe given as,
[tex]\begin{gathered} n!=(n-1)(n-2)! \\ W\text{here n is the number of jurors } \\ n=12 \end{gathered}[/tex]Therefore,
For 12 jurors we will have the number of ways as
[tex]\begin{gathered} 12!=12\times11\times10\times9\times8\times7\times6\times5\times4\times3\times2\times1 \\ =479,001,600\text{ ways} \end{gathered}[/tex]Therefore,
12 jurors can be assigned seats in a courtroom in 479,001,600 ways
