In how many ways can 7 directors sit round a table
A.720
B.120
C.24
D.5040?
Answer
To find the number of ways the 7 directors can sit around a table, we can use the concept of circular permutations.
For a circular permutation, the number of ways to arrange n objects around a circle is (n-1)!.
In this case, there are 7 directors, so the number of ways they can sit around the table is (7-1)! = 6!.
Calculating 6!:
6! = 6 x 5 x 4 x 3 x 2 x 1 = 720.
Therefore, the correct answer is A. 720.
