The first person to choose a seat can choose any of the 6 seats.

The second person can choose any of the 5 remaining seats.

The third person can choose any of the 4 remaining seats.

The fourth person can choose any of the 3 remaining seats.

Now, we do 6 x 5 x 4 x 3 to figure out the total number of ways they can sit in the seats.

6 x 5 x 4 x 3 = 360 ways
