Let's say you have a binomial problem. P is 20% and q is 80%. n=100. If the question asks for the probability that a success is 95% or greater, how do you set it up? I did 100 choose 0, 1, 2, 3, 4, and 5. I added the answers together and subtracted from 1. I did not get the right answer. Can someone tell me where I am going wrong?

Thanks.

Thanks.
