You flip 9 fair coins. Amazingly, the first 8 flips all come up heads. What is the probability that the final flip will be a head too?

OpenStudy (anonymous):

assuming it is fair, then it is still \(\frac{1}{2}\) right?

OpenStudy (anonymous):

oh, it says "fair" ok fine definitely \(\frac{1}{2}\) the coin has no memory
