Respuesta :

The number of ways they can be seated in a row if both families want to sit together is 2 ways

Given that two families with four people in each family go to a movie theater, in order to determine the number of ways they can be seated in a row if both families want to sit together

We will use the permutation rule since it is about the arrangement.

We will take 4 people as 1 group and the other 4 people as another group.

If the groups are to sit together, the number of ways this can be done is 2!

2! = 2 * 1

2! = 2ways

This shows that  the number of ways they can be seated in a row if both families want to sit together is 2 ways
