I am attempting to help my friend with statistics homework, but I never took statistics. She doesn't really have another person to ask and since I'm pretty good at math I figured I would try to figure it out. This problem has me stumped, however. I don't want to just be given the answers to the homework so I am going to present an example question:
Let's say that when a magic coin is flipped, it can land heads or tails like any other coin. However, this coin is magic and is rigged in favor of a specific side. The coin can only land on heads 1/250 flips. In 5 independent cases, what is the probability that exactly 4 land as tails?
No need to actually solve the problem, just tell me how to do this specific kind of problem. I just didn't know how to word it without providing a specific example.
