Six friends, four boys, and two girls went to a movie theater. They wanted to sit in a way so no girl sits on either first or last chair. How many such arrangements are possible?

Answer :

Answer: 5 valid arrangements

Step-by-step explanation:

This depends on whether the boys or girls swapping places are considered unique solutions.  I'm going to assume that is no, because there would be an unrealistic amount of solutions if it is true.

Assuming G = girl and B = boy, these are the possible arrangements.

(I will bold the valid solutions).

Thus, there are 5 valid arrangements.
