    Answer:

    Step-by-step explanation:

    well if alan and debra are in separate class rooms.  They would have to add up the number of movie students in each class room   alan has X movie students and debra has Y movie students

    Mean number  =  Average number  =   sum of the values / number of values

    Mean number =  (X + Y) / 2
