How many different ways could seven birds perch around a circular bird bath? a) 5,040. b) 4,320. c) 721

720

Step-by-step explanation:

Seven birds perch around a circular bird bath.

Here we have to use permutation because we need to arrange the seven bird.

In circular arrangement. for n number of object. It would be (n-1)! because last object would be identical to first one.

In circular permutation, Number of object reduce by 1.

Here, we need to find number of ways of seven birth around circular bath.

Total number of ways = (7-1)!

⇒ 6!

⇒ 6x5x4x3x2x1

⇒ 720

Hence, 720 ways could seven birds perch around a circular bird bath.
