In how many ways can 4 people sit next to each other in a movie theater row?

Solution:

Given, 4 people sit next to each other in a movie theater row.

We have to find the number of possible ways.

The first seat can be any one of the 4 people.

The second seat can be any one of the remaining 3 people

The third seat can be any one of the remaining 2 people

The fourth seat is the last remaining person.

Total number of possible ways of seating in a row = (4 × 3 × 2 × 1)

= 12 × 2

= 24

Therefore, the total number of possible ways to seat is 24.
