How do I set my equation up? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 80C6*(0.15)^6*(0.85^74)
How many ways to choose 6 from 80, and each of those 6 has a 15% probability; each of the 74 has an 85% probability. The expected value is 80%0.15 or 12, so this will be a small probability, both because the probability of each individual one is low and second because it is not near the expected value.
It is 0.0205
