I am stuck on a problem for my stats class. I have not done any work but I will explain why. Here is the problem;
- A coin is flipped until you get a tails. What is the probability of getting at least 4 heads?
I have done probability with coins before, but this question stumped me. How? Because we only have ONE coin, and we don't know how many times the coin is tossed. I know that with one coin, the probability of getting a head is 1. And the number of outcomes is 2. However, I don't know the next step after this, especially when I'm not given information on how many times the coin should be tossed.
Any help would be great. Or maybe just a tip on looking at this problem from a different perspective? Thank you!
