Hello I am in need of urgent help with a problem that involves permutations. The question goes as follows:

The Northeastern University College of Computer and Information Science has 5 women and 20 men who are full-time faculty members. Their photos are to be displayed in a single row at the entrance to their building.

iii. In how many ways can the photos be displayed so that no two women are adjacent? Hint: Consider arranging the men’s photos first and then placing the women’s photos among the men’s photos so as to ensure that no two women are adjacent.

I'm not sure where to start on this one, any help would be greatly appreciated. Thanks!
