Say that every single class in Full Sails Masters Degree in Game Design has a 5% failure rate per month. Say also that when a student fails once, he or she drops from the program. There are twelve months. Given a cohort of 100 that starts the program, about how many are left after twelve months? Remember that someone can only pass or fail.

Answer :

If there is a 5% drop every month, then the class becomes 1-5%=1-0.05=0.95 times the previous size.

The formula for [tex]t[/tex] months would be
[tex]100*0.95^{t}[/tex]
so for 12 months it would be
[tex]100*0.95^{12}\approx 54[/tex]
