Question

In how many ways can $12$ people be seated around a table?

• A. $11!$
• B. $12!$
• C. $\frac{12!}{2}$
• D. $1$

Answer 1

The correct option is A $11!$

Number of people $=12$

When in circular arrangement

The possible number of arrangements of $n$ objects around a table (circular) $(n-1)!$

Therefore number of ways of arranging $12$ people

$\Rightarrow (12-1)!$

$\Rightarrow 11!$ Ways

Therefore number of ways $=11!$
