Question

In how many distinct ways can 5 people sit around a round table

Answer 1

Step-by-step explanation:

1. there are 2 way to seat B
2. 3 ways to seat c
3. 2 ways to seat D

and one empty seat before

so you see there are 12 ways for A and B to sit together and 12 ways for them to sit a part, which account for all 24 ways

the five people can sit around the table.

so

the no. of ways 6 people can be seated around a round table becomes 1×5×4×3×2×1=120

in other words it is equal to (n-1)!
