A class photo is being taken of six students, sitting in a row. Three of the students are Jamie, Marshall, and Susan, and Jamie wants to sit between Marshall and Susan. (This also means that Jamie is next to both Marshall and Susan.) How many arrangements are possible?

(MJS) and 3 others  

4! = 24

 

(SJM) and 3 others .. also 24

 

so that is 48 possible arrangments.

 

If you want me to explain more then just ask :)
