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.

The monthly failure rate is q = 5% = 0.05
The monthly pass rate is p = 1 - q = 0.95

We want to determine the probability of 12 passes in 12 consecutive months for a student.
P(12 of 12 successes) = ₁₂C₁₂ p¹² q⁰ = 0.95¹² = 0.5404.

Therefore if we have 100 students, the number that gets through 12  consecutive months is
100*005404 = 54 students.

54 students are left after 12 months.

There is nothing there

The answer is 41.7 because 1.39 times 30 is 41.7
