Permutation and combination define the arrangement of the objects. The 8 people can sit in 1440 ways on the circular table.
What are permutation and combination?
Permutation depicts the arrangement in order and the combination tells the ways to select the object from that group.
Total number of people = 8
People who want to sit together = 2
Remaining people = 6
Total arrangements of 6 individuals and 1 group have to be done on the circular table. a number of ways to arrange them = ( 7- 1 )! = 6! ways.
A total number of ways 8 people including 1 group can be seated as
= 2×6!
= 2 × 1 × 2 × 3 × 4 × 5 × 6
= 1440
Therefore, there are 1440 ways to seat 8 people.
